@xpgong You usually only need the prior year AGI to efile. After you file each year you should save both the .tax2020 file and the PDF file. If you have the pdf you don't need to open it in the program. Don't you have a pdf?
You can request a transcript from the IRS

And if you transferred from the prior year .tax2020 file everything should transfer over for you.
If it's asking you to Activate again,
Make sure your computer is the same way when you originally installed it. Like with no flash drives plugged in or plugged in if one was. It asked me again so I just closed the program and took out a flash drive that was plugged in and tried again. It worked. Or you may need to connect a flash drive or printer or something that was connected when you originally installed the program.
The License Code just started with 2019. It was a 14 digit code then.
And what other tax company can open prior years with the current program? That would be impossible.
