Same issue here. I had updated my phone number this year to a German cell number which TurbotaxOnline accepted when I logged on this year (my 9th year of using TurboTax). When I got to the e-file i receive the error above. Thinking it was the phone number on my account, I deleted the number and tried again to e-file. Same error.
Please tell us there's something being done to resolve this issue or this regular customer won't be here next year.
