I reinstalled TurboTax 2019 on the computer where I was stuck in the state download loop and then copied the state folder (kyi_19) from the computer where TT was working and voila - IT WORKED!
I can access the state, view forms, etc.
Great suggestion djboyag!
I'm sure many people don't have that option if they only have one computer for example.
I hope TurboTax support staff reads this thread and figures out the source of their problem.
