Having the same problem, this time with a license code provided by TurboTax support because their online software has a bug that no one can help me with. I, too, have already tried the browser refresh, clearing cache and cookies, different browser, and different device. (So help me, that appears to be the only thing TurboTax Support can ever suggest.)
I've also tried setting my mailing and billing addresses, and that is also not working.
