I'm e-filing 2 state returns, but TurboTax only asks for one state's driver license info. How can I enter the 2nd state's driver license info? I'm using Deluxe for Mac.

Are you efiling 2 states for the same taxpayer? Only one license should be necessary unless you are getting an error.

Yes, I'm filing for a single taxpayer to AZ and CA. TurboTax listed instructions for both states that said that providing license info was not required, but desired for both states to help with identification and prevent unnecessary delays. There is no error indicated when I get through the reviews. 

If there are no errors, you should be able to e-file. What are you having problems with?
