This answer works!
Change your phone number to a US number in the Intuit Account of Turbo Tax. This solved my problem. No need to verify this number in the Intuit Account just click exit when your are done. Then go back to you return an continue filing.
Just make sure that you change the phone number in the Intuit Account of Turbo Tax not in the turbo task website or filling doc. You´ll receive a code on this US number that you need to enter in the intuit account and then go back to your turbotax page to continue filling!
