Have used TT2020 Windows desktop and filed in Apr, 2021. Now, in 2022, bought and installed TT2021 Win Desktop.
Need to go back to look at my 2020 return by running TT2020 again. Before it runs, it forced me to update, although I did not need to. After TT2020 was updated, it asks for license code, which, of course, I can no longer find.
Questions:
What can I do to regenerate 2020 1040? using TT2020?
My TT2020 was a licensed copy, why do I need to enter license code again?
Why was I forced to update TT2020, which, of course, could change what I filed?
