Yes you can transfer from any .tax2021 file. Every year I transfer several test files that are not finished or filed. You need the file ending in .tax2021 to transfer. In Windows it should be in your Documents then in a Turbo Tax folder or search your computer for all files ending in .tax2021 or .tax. 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.
