Thank you for the reply. However, I did not need to reinstall the software nor do a manual update. As I suspected the problem resided outside of my control - an apparent program bug. Seeing comments from other 2024 Turbo Tax customers who experienced the same problem, one recommendation was to simply wait a week for a typical program update.
And that is what I did. Today I opened Turbo Tax 2024 and it applied updates that completed without any errors. I then loaded my saved tax file and was able to finish it, e-file my Federal taxes, and print out my state taxes for filing without any problem. - The IRS accepted the e-filed return today.
Whatever the problem was, it was resolved through today's program update. I needed to do nothing but be patient....
