Get your taxes done using TurboTax

@LenaH  Thank you so much.  My updates are all up to date, and I had already followed the "Troubleshoot..." steps without any luck.  Then I tried going to the TT exe location after reading your instructions, and ran it as Administrator.  For some unknown reason, it opened!!!  Last Friday it was suggested that I run "File Indexing" which took awhile, and I hadn't tried anything else all weekend, so maybe that helped to clear whatever was going on??  Anyway, all is good for now.  Thank you.
