The info has disappeared from my desktop 2022 TurboTax program. How can I get it back?

When using the TurboTax desktop editions any tax returns you saved and a PDF's you saved will be in the TurboTax folder of the Documents directory.

If you used the desktop CD/Download editions installed on your computer, the only copy of your tax data file and any PDF's will be on the computer where the return was created.  TurboTax does not store online any returns completed using the desktop editions.
