TurboTax uses phone numbers for identity purposes so it may be looking for an old phone number you've previously entered. If it is not recognizing any of your current numbers, you will want to update the number. Here are the steps (from https://ttlc.intuit.com/questions/1900724-how-do-i-update-my-turbotax-account-information:(
"To update your TurboTax (non-Advantage) account email, phone number, mailing address, or password:
- Sign in to TurboTax and select Intuit Account on the left, just above "Sign Out" (you may need to scroll down; click or tap the 3 white lines or Tax Home if you still don't see this).
- This will open your Account.
- Select Edit next to the information you want to change."
When you return to the form to purchase after changing your number, it should recognize the new one.
