If you used the Desktop program the only copies of your return is on your computer and any backups you made. You should have saved your return as a pdf file. If you don’t have the pdf you should have the tax data file ending in .tax2021. Run the 2021 Home & Business program and open your return. Go up to File - Open.
The .tax files 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.tax2023". That file is if your computer crashes or your real file gets lost or deleted or corrupt so you can restore it.
Why do you need to resubmit it? Did it reject and didn’t get filed? Or were you supposed to print and mail it?
