There is no way to transfer information from last year's tax return without the .tax2021 file. When you use the CD/Download TurboTax software, the only copy of the file is on the computer that you used, and any backup copies that you made. TurboTax does not have a copy of it. If you don't have a backup of the .tax2021 file you will have to start your 2022 tax return from scratch, as if you didn't use TurboTax last year. You will have to enter all the information manually, as it is called for in the Step-by-Step interview.
