You can only do a 1120-S return using the Windows Desktop Business program so it’s only saved on that computer and any backups you made, not Online. You should have saved both the pdf file and the data file ending in .tax2024. By the way, A business return file ends in the same .tax2024 as a personal 1040 return. It should be in your Documents in a Turbo Tax folder.
Or you could have used the Turbo Tax live expert help service which is a lot more expensive and only done online.
