@LField's solution worked for me (I also am an overseas user, in my case I had a Japanese cell phone number).
I do have one thing to add: simply removing the overseas number and leaving the number blank in your Intuit account does not solve the problem. Once I added a stateside number AND verified it, the tax return went through.
Thank you, @LField, for adding your experience--it got me 90% of the way there!
