Try this workaround from @Critter (Max benefits for overseas filers) :
This is caused when the MAX bundle is in the order and there are issues with the information entered in the Personal Info section. This can happen in the following situations:
- You have a foreign mailing address entered, but are paying with a U.S.-based credit/debit card
- The first name you've entered is only one letter
This can be resolved by temporarily changing your information under Personal Info, then changing it back before filing your return. If you have a foreign address, enter the U.S. billing address for the card you're trying to use. If you have only one letter as your first name, change this to your full first name, as shown on your social security card.
- Click on the Personal Info tab at the top
- Make the necessary changes to your personal Information (address)
- Click the File tab at the top and click Start next to Step 1
- Continue to pay for TurboTax Online
- Continue through the interview until, in Step 3, you've signed the consent form for MAX Assist & Defend
- Return to Personal Info and set your mailing address back to the correct address, as described in steps 1-3, before transmitting your return
If you've followed the above steps and you continue to get the error message, it can be resolved by removing the MAX Benefits from your order, which will allow you to file.
Note: If you choose to remove the MAX bundle and file, you will not be able to order it later.
