My resolution after going through this process way too many times was to delete the address and city. I did this after clicking Review on the left sidebar > Check Info button. When take through the process of reviewing error on the State (only), I deleted the address (instead of entering it). I had to do this when reviewing again and the city appeared. I deleted that as well. Then the system said I could efile.
The Turbo Tax free edition isn't intuitive AT ALL. There should be a popup stating to delete the contents. I hope this helps someone! 🙂
