I had the same issue today. I used some of the advice giving. I went to my Intuit accounted deleted my Germany number that verified there and changed it to my U.S. vonage number. I refresh the Inuit account and went back to my TurboTax account and changed it there too. File again, this time it asked me to verify the vonage number my text or voice. I verified by voice and was finally able to submit and file my returns. I hope this helps.
