I do not have an active US phone number. I am a service member stationed overseas and have gotten a foreign number that cannot be registered. How do I proceed?

I cannot leave the Phone number block unfilled. This should not be a required field.

You are right, a phone number is not required to file a tax return.  However, for some reason, TurboTax requires this it e-file the tax return.

Enter any phone number with a valid US area code, such as (202) 222-2222
