I came across a similar issue. I nailed it down to the file extension ".tax2021" If you are in Windows 10 or 11, the security system triggers a block when either trying to print the file or save it. I managed to save the file if I saved to the desktop, but if I tried to save the file to the default folder it said the file did not exist. As far as I can tell Turbotax has built is some kind of detection of a cloud based file back up such as Onedrive which it deems as unsafe. Also the PDF view/print would not work either. Shoots up an error message.
