Another way to look at it ... the 2021 information can be transferred into the 2022 program but the same 2021 tax file cannot be transferred into the 2021 program OR opened by the 2021 program. This is the same for all transfers between all tax programs that allow such transfers. Although the prior year info can be "transferred" to the next tax year so the basic info is populated the tax file itself cannot be opened by a program that did not produce the original tax file.
