When I try to "File your returns" it asks for Driver's License, I enter the info and press continue and it goes back to the file your returns screen. How do I continue?

Close TurboTax, clear your Cache and Cookies, open TurboTax and return to the File section again.

Basically, your Driver's License is not required to Efile a Federal Return, but if you skip entering the info, you may need to print and mail your State Return.
