Thank you so much @SteamTrain for your ideas.
Unfortunately I tried everything you suggested without success.
However, I did try selecting ONLY filing the federal return (selected to file Georgia state return later). The federal return transmit succeeded. Then I selected just to file the Georgia state return, and it gave the same update validation failure for the state transmit.
So.... it appears the failed validation update error is with Georgia, not Federal.
I will contact TTS as you suggested.
Thank you.
