For the phone number, if it's not a U.S. phone number, you can just leave the phone number blank.
Also, be aware that if you plan to pay your TurboTax fees with a credit or debit card, that card MUST:
- Be in U.S. Funds (dollars)
- Have a valid U.S. Billing Address
- Have a valid U.S. phone number tied to it.
Otherwise, the credit/debit card will be rejected for payment.
