@sandy4042 I don't know the internals of TT, but have used it for years. I have a spreadsheet that predicts taxes and in most instances through the years it has matched TT. So I think TT recalculates everything after an update.
However, last year when we had similar 2210 problems the posts talked about deleting the form (you can do that in the forms mode) and reentering the data. I would definitely do that if I had used some of the workarounds and 2210 TT calculations fixed annualized the Capital Gains and added the Charitable Deduction. I have filed, so I don't know what has been fixed since middle of March.
Hope this helps.
