I have same issue.
Had 2019 taxes completed but not filed (saved as turbotax file, unfortunately as pdf)
In 2022 went to re-open, to complete and file- turbotax said it needed to update the software
Which I did.
However now it will not open the 2019 tax file. All is lost. I don't have a pdf backup.
State is not an issue, as no state income tax, just need federal.
