So I went to file today and was receiving this error when I tried to use my credit card to pay for state filing "Unable to sign you into TurboTax Cloud. Please check your sign-in info and try again."
The kicker is that it has to be security related because I changed my PC's DNS addresses to 1.1.1.1 and 8.8.8.8 and everything worked fine. Submitted perfectly, both Federal and State. Only after getting super frustrated did I find a support thread mentioning something similar.
