The windows Desktop program does save temporary files that start with a ~ sign. The ~ is a tilde file. Those are temporary files that you normally don't see and normally are deleted. But now Turbo Tax is leaving them in the folder in case something happens like your computer crashes. Then you can go back.
If you don't want it to be saved then first thing after you open it is save it with another name. Then you will be working in a copy. Or make a copy in Windows Explorer and give it a different name. Then open the new copy.
After I file I save my file and add FINAL to the name. And also save it after I update the efile status that shows Accepted. Go up to File-Save As to change the name. Then copy it to another place or external backup.
