Please review the Opening Balance transaction in your register. If you recently had to reauthorize your account, a bug in the process may have incorrectly changed or added an incorrect transaction.
To correct a bad Opening Balance restore a data file backup taken a few weeks ago, before all this happened. Restore the file to a different file name than your current data file (you do NOT want to overwrite your current file!). Open the restored file and look at the account's Opening Balance and write down the date and amount.Now switch to your current file, look at the account's Opening Balance as it stands now. If different, edit the transaction and change the amount to what you have written down.
There may also have been duplicate transactions downloaded and added to the register. These duplicates need to be found and deleted.
About the Opening Balance transaction in your register:
Make sure that the "Opening Balance" transaction in your register - always is the oldest transaction by Date - occurs only once in your register - its amount matches the bank statement balance shown on that day - if you owe money in a credit card account, the Opening Balance transaction as shown in the register must be a negative amount, e.g., $-123.45 - the transaction is marked "R"(reconciled) in the "Clr" column - uses the same account name, surrounded by [square brackets], as Category as the account it's in (e.g., Opening Balance transaction in your MyChecking account has Category = [MyChecking])
If the Opening Balance isn't correct, your register balance on any given day will never match the bank's balance on the same date and your register will never reconcile correctly.
* that's called a "transfer back into the same account" and is OK. Quicken uses this method to establish the Opening Balance without making it appear as an Income or Expense in any views or reports.
CRRen said: I have done that. As I keep repeating, the software incorrectly subtracts charges from the balance when it should be adding them. It incorrectly adds payments when it should be subtracting them. This is very easily seen by looking at the balance column in the register for each transaction. Any modification to opening balances just exacerbates the problem because the software is not doing the math correctly for this one credit account. Duplicate entries are easily found and would not cause this kind of error even though a duplicate may cause a balance to be wrong. I am now going to create a new credit account with the correct opening balance and activate that. I will have to enter a modified amount in the old credit account to zero it out and deactivate it. I really don't like having to do this. Something has occurred to make this happen.
Can you please capture one or more images of the parts of your account register showing the issue, sensitive information blacked out as necessary to protect your privacy but annotated to describe the situation, and attach the image(s) here? Include the entire register portion of the Quicken window together with column headers.https://community.quicken.com/discussion/7867159/faq-how-do-i-post-a-screenshot-in-the-community-from-windows

Please save images to files of file type PNG, JPG, or GIF only. They're easier to work with than PDF files.
