Can I use the same phone number for 2 accounts?

I don’t have a USA phone number and I want to use my fiend’s number

I am not sure but I doubt there is such a restriction, provided the number is a U.S. phone number.

Because you cannot enter a foreign phone number in TurboTax, Tax Expert Alumni @KarenJ says recommends using a friend's phone number. Make sure you get their permission.

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.

Tax Expert @HeatherPLO says you might try to disable the Two Factor Identification instead of using a dummy number so you won't receive codes on your phone.  Please see the Help Article here for more instructions on how to do this.

Although a phone number is not required on a tax return, the TurboTax program requires a phone number to be entered before the return can be filed.

A foreign phone number cannot be entered.  You can enter any phone number with a US area code, for example (203) 222-2222
