That is NOT how your 6-digit authentication works! Switching to "code sent to text" does not let you avoid having your 6-digit verification code sent via email AFTER you've already logged in and trying to File. This is a ridiculous flaw in TurboTax verification process - by the time the code arrives 15-20 minutes later (which is 20 minutes of my life wasted), TurboTax logs you off the session, and if you were to go back, the code that you've waited 20 minutes to get has already expired!
