I was finally able to get it to work using the suggestion to update the screen resolution to 800x600 and then gradually worked my way up to 1280 resolution - each time generating the pop-up screen to log in. Even then, I could see the Name/Password fields but could not see the cursor or any characters in the field when I typed. Additionally, I received a text at the same time I hit enter from Intuit with a verification code. Without doing anything else on my computer I typed the numbers on my keypad and pressed Return (there was no popup or entry screen displayed so I had no idea if what I was typing would work). Luckily, it worked!
I feel like this was more luck than anything - TurboTax needs to provide a workable solution that any legitimate software company should be able to provide. User Interface errors with screen resolution issues are junior level coding mistakes that can't take weeks to fix.
