Are you on Windows or Mac? Dies your return show up in the box like above? Or go up to File-Open and try to find it. Did you search your whole computer for all files ending in .tax2021? And check the recycle bin and your backups. Check in One Drive, 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 *.tax2021 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.tax2021". That file is if your computer crashes or your real file gets lost or deleted or corrupt so you can restore it.
When you find your file you can also get to Amend another way. You can find Amend under
Federal Taxes or Personal (for Home & Business)
Other Tax Situations
