Solved
I'm getting errors down the line about foreign taxes, which I don't have any of, so I think they are related to this error.
If you haven't already done this, then, with TurboTax open:
- Select the dropdown next to Personal Info, then Review/Edit
- Select My Info in the left pane
- Scroll down and select Edit to the right of Mailing address
- In the Type of mailing address box, select the dropdown and make sure you select U.S. address
- Make sure that your street address, city, state and zip code are correct, then select Continue
Close and save your return, then open TurboTax again.

Enter your E-mail address. We'll send you an e-mail with instructions to reset your password.
