The quickest and easiest would be to edit these transactions and put in a date of 12/31/2016 in your case. That makes the transaction appear in the correct tax year.
I don't know why the dividends would come down to you as uncategorized - my broker always reports them as dividends, but you certainly can recategorize the dividends as "dividends" if you wish. Just edit the transactions and re-enter the amount in the dividends box.I typically have a few January dividend payments that are considered, for tax purposes, as prior year dividend but generally I just leave them alone since reconciling to my broker statement is more important to me than getting an internal Quicken tax report correct, and the broker's 1099-DIV does provide the correct information in any case.
My personal preference for this event;I have a brokerage holding account - it normally has a zero balance.Record the dividend income to the holding account - predated 12/31/TY.On the date recorded by my FI - transfer the cash from the holding account to the regular brokerage account.The advantages are; The tax reports are correct.The cash balance in the regular brokerage account is always in sync with what the FI reports.
How would I "supply the _DivInc category for the MiscInc field"?
