After you file

TurboTax does not support tax years prior to 2020.  So even if you can find software from another vendor for an earlier tax year there will not be any updates nor state programs available from TurboTax.

 

There is company that will take the old tax data files and produce a tax return but there is a charge for the service and the company is not associated with TurboTax nor recommended by TurboTax.
