Are you on Windows or Mac? When you start the Desktop program it should show you all your returns and ask if you want to continue. If it doesn’t find your return go up to File-Open and you can browse to where it is.
The Turbo Tax data files end in .tax2024 and in windows should be in your Documents then in a Turbo Tax folder. Or search your whole computer for all files ending in .tax or .tax2024.
And check the recycle bin and your backups. Check in One Drive, Drop Box, etc. It should be in your Documents then in the Turbo Tax folder. Also if you have multiple Windows user accounts, log into each one and do the search for the *.tax2024 data file from within each one and checking the Recycle Bin in each one.
If you don't have the main .tax file you might have one that starts with a Tilde sign ~ like "~your name.tax2024". That file is if your computer crashes or your real file gets lost or deleted or corrupt so you can restore it.
