I have tried all of the things suggested here. I have enabled third-party data transfer. I have also tried turning off two-step authentication. My firewall is off. I have called Morgan Stanley and they said it was TurboTax. There's no-one/nowhere to call at TurboTax.
I've paid for this program so I can import this data easily and electronically. Now I've wasted a lot of time trying to find answers to something that shouldn't even be a problem. I have never had this problems before.
What else can be tried?
