Same issue. Talked to them twice. They say it's my internet connection (which is fine), my browser (cleared history and cache) maybe my credit card (confirmed with the bank it's not) - they wanted me to try a different credit card (same error) or give me the number to their collections department. When I asked if there was a problem with my account and they said no, but maybe collections had some ideas. I asked for a supervisor, was placed on hold and got a message saying it would be a 45-50 minute wait. I'm really over TurboTax.
The error is on their end and they don't have the answer. And they really don't care.
