It is saved when you save it. It is not saved in the program. Are you on Windows? It should be in your Documents then in a Turbo Tax folder. Did you save it as both the pdf and .tax2022 files? Search your whole computer for all files ending in .tax or .tax2022.

Did you save your return? In Windows you have to manually save, although it will ask if you want to save when you exit the program or switch to another return.
If you don't have the main .tax file you might have one that starts with a Tilde sign ~ like "~your name.tax2022". That file is if your computer crashes or your real file gets lost or deleted or corrupt so you can restore it.
