Why won't it accept my driver's license information?

No one can see your screen or your tax return.   Are you paying careful attention to the lines to enter the expiration and issue dates and using the same format that is used on your DL?   You are not even required to enter a drivers license to e-file your federal return.   It just adds another level of security---you are allowed to skip it.   Some states are pretty fussy about the drivers license though so you might need it for the state.

Check to see that you haven't mixed up the letter "O" and the number zero "0". Similarly check to see that you haven't mixed up the letter "I" and the number "1".

I think the number one mistake is mixing the "issue date" and "expiration date"

Also, try entering the license number without spaces.
