I finally had time to uninstall and reinstall the TurboTax application for Mac per the instructions in the link. A bit tedious and annoying to be sure; took me the better part of an hour to remove all the pieces and parts, reinstall then test the application with a return that had not yet been filed. Fortunately the effort was successful and I can now create .pdf copies of returns in advance of filing. Since I originally installed the app from a purchased CD, this time I downloaded the application from Intuit using my license code just in case the CD is defective. Thank you, AkinaLO for your helpful response.
