You have to have a valid US domestic 10-digit phone number in both the return and in the Intuit Account settings. Or it "may"also be possible to leave the Intuit Account phone number blank.
If you browse this entire long thread, you'll see what other users with this error code did to be able to efile. Some of them may be able to help you.
