I have the exact same issue as Mike. [I am an experienced TT user for 25+ years, and also a computer savvy professional and clearly there is some TT bug that is affecting us both].
On Windows 10 desktop, these are the two issues:
1. TT2021 cannot transfer a 2020 return (it shows a pop-up that goes away in a few seconds and nothing happens). It does this with multiple different returns, different versions of the same return, and saved copies returns on different media (USB, CD-ROM and hard drives).
2. Actually, TT2020 cannot even open the return that was filed by it a year ago (I filed three different returns and has the same issue with all of them and it says Error reading the tax file).
I have tried the links provided by Carissa in a separate thread and they have not helped yet.
Thanks,
Neil
