You cannot enter a foreign phone number in TurboTax. You can leave the field blank or you can enter the
phone number of a relative or friend in the U.S,, or a "dummy number"
(800-555-1212). This will allow you to complete your return, and the IRS will
identify your entry as a placeholder number - if they have questions, they will
mail them to you." The IRS does not call taxpayers anyway.
Please note that you will need a US credit card with a US billing address to pay for TurboTax.
