Thanks for your suggestion xmasbaby0. I ended up contacting TurboTax Support via DM on Twitter. With their help, we figured it out. What worked?
Edit Address Info, change the 'Type of Mailing Address' to 'US Address', then delete everything.
Then change it back to 'Foreign Address' and delete everything.
Then change back to 'US Address' and enter the correct info.
That fixed it.
