@JES33 Whenever you exit your TT program, it will ask you if you want to save the file (even if you have not made any changes). If you answered YES after you e-filed, it will have updated the data file used in your e-filing in whichever folder that you have saved your 2021 tax files (PDF, .tax). The date and time stamp on the files should correspond to when you last saved your PDF and data files.
Look up that folder on you Mac and the file with the extension .tax2021 is your data file. Make a copy of that (and the PDF of your return and worksheets) on a thumb drive or wherever you backup your important files. That way, whatever happens to your Mac or should the TT program be corrupted, your files can be loaded from that safe-keeping copy.
