This and many other built-in categories (the ones starting with an underscore and a few others) are undeletable but can be hidden.
Go into Tools / Category List.At the bottom of the Category List view make sure "show hidden categories" has a checkmark.On top of the view select "Show Full List"In the left column click "All categories".Scroll down to near the end of the list where the _401... categories are.If there is a checkmark in the "Hide" column click it to unhide the category.Do so for all other _... categories with a Usage count greater than zero.
From C. D. Bales:Assuming you are making your 401k contributions using a pre-tax deduction in a Quicken Paycheck transaction, the _401Contrib "transactions" are in a hidden Quicken account named "Tax Impact of 401(k) Accounts". You will not normally see transactions in that hidden tax account, but you can see them in both the Tax Schedule and Tax Summary reports.In the Tax Schedule report (assuming you're looking for "your" contributions); they will appear in the W-2 section under "Salary or wages, self [Your Paycheck Name]".In the Tax Summary report (subtotalled on Tax Schedule) (assuming you're looking for "your" contributions); they will appear in the W-2 section of the report, under "Salary or wages, self [Your Paycheck Name]".I don't think you will typically see the _401Contrib category in the Tax Planner; those who use the Tax Planner can correct me, if I'm wrong. Your 401k pre-tax deductions are recorded as transfers from the paycheck deposit account to the 401k account. Those transactions should appear in the Tax Planner in the Wages section. Clicking the "Hide Details" link in the Wages section should display the actual and scheduled contribution transfer transactions for Wages and Salary, if the "Quicken Data (from CCYY)" radio button is selected.
I have the problem where _401Contrib is no longer showing up as an offset to my gross income. It disappeared from Quicken 2017 last year when I started a new job and created a new detailed version PayCheck entry. I first noticed this when I imported tax info into TurboTax - normally W2 would populate correctly by accounting for 401k contributions. Then I went into Tax Center (both in the Tax Planner and Taxable Income YTD) and verified that no negative offset _401Contrib transactions are being recorded.Another way I can verify this is going to transaction list, scrolling down to the _401Contrib line item. It shows 472 count in the usage column. If I click on this number and hit recategorize, I will get a table report of all the 472 _401Contrib entries - all of my 401k entries over the years. The last one is for 1/21/17 which was the last paycheck entry for my old company entry. None of the entries for my new job are showing up. I have changed nothing else - paychecks have a pretax xfer to a 401k account. I tried deleting and recreating the 401k account. I tried recreating the paycheck entry. The problem remains. I have also ran validate checks on my data file - no issues reported. And just to be really clear, it matters not whether I hide or unhide the _401Contrib entry in the Transaction list. Something is broken.I saw in another closed post from 4 years ago that there have been reports of spouse income entries getting screwed up and/or possibly screwing up the my income entries. I do also track spouse income, though no 401k -- might be related somehow... ? Interested in ideas on how to resolve.
There were issues with paycheck reminders in early releases of Quicken 2017.
Can you provide more background on the datafile and the paycheck? For example, if the datafile was converted to Quicken 2017 format from a prior version, which version and do you have access to the backup that was saved? Do you recall whether you deleted the original paycheck reminder before or after creating the new paycheck reminder or did you simply modify the existing paycheck reminder?
As you installed Quicken 2017 about 4/17/17, is it likely you created the new paycheck reminder used to enter the 3/10/17 Company B paycheck transaction using Quicken 2016? Note: There is no datafile conversion when we upgrade from 2016 to 2017.
Is it possible you didn’t use Add Pre-Tax Deduction > 401(k)/403(b)/457 when you created the new paycheck reminder?
Regarding validation, did you perform the Copy your file and Validate?
