After you file

You did not answer my question. My 2020 TT return was done on a 32 bit system. 2021 TT, which I loaded, is a 64 bit system. It is not recognizing my 2020 return. It's a shame TT didn't prepare customers for this. I now have lost all of my prior TT records


The 2020 tax data file can only be opened by the 2020 TurboTax program.  Whether your computer uses 32 bit or 64  bit is not relevant.  The TurboTax software can be installed on either.

The TurboTax program for 2021 cannot open the 2020 tax data file.  The 2020 tax data file can only be transferred to a New 2021 tax return.

 

I am using the a 64 bit system and have TurboTax software installed from tax year 2009 through tax year 2021.
