I unlocked several returns and the background color is null/white, like normal.  I updated the 2020 program and tried various things.  But note:  my 2021 program wouldn't update the 1040s so I followed one of your suggestions I found online and deleted the 1040 and reinstalled it and it updated.  Another note:  My rates per form didn't transfer either so I entered them all in manually.  Due to all this I think there may be a few corrupted files in my original download.  I will live with it this year since I don't want to go back in and re-set everything (letters, rates, invoices, etc) the way I want them.  But if there is a way to update it all but the common file....I'm for it!
