There still should be a saved file from before. The times before did you say to save when you exited? I would look around. The tax files (and PDF files) should be in your Documents then in a Turbo Tax subfolder. If you can't find them do a search for all files ending in .tax or .tax2021 or .tax2020 etc. And check the Recycle Bin. For Windows 10 check the One Drive. Did you make any backups? Like DropBox.
If you don't have the main .tax2021 file you might have one that starts with a Tilde sign ~ like
"~your name.tax2021".
That file is if your computer crashes or your real file gets lost or deleted or corrupt so you can restore it.
