i'm using the CD software that is installed on my computer when I did my 2020 taxes. When I tried to go into the 2020 turbo tax from my desktop, it requested an activation code. I entered the code and the answer was that code has already been used. Of course it has, I used it. Why doesn't the program recognize that? I need to amend my 2020 and 2021 returns before I can file the 2022 return. I have all three programs installed on my computer. I haven't tried to open 2021 yet, because 2020 has to go first. How do I fix this?
