After 1 1/2 hours of internet searches, modem reboots, and various other attempts, my problem accessing my TurboTax account without reentering my activation code was unbelievably fixed by removing a USB drive I had inserted earlier this morning! Thanks to @Hiram413 for making the suggestion that I never would have considered. I'm shocked TT publishes such widely used software with such a major glitch, but very thankful for those on this forum willing to share their ideas and experiences.
