It took me 5 submissions but got it to submit with NO reference to AGI. I assume that since TurboTax requires a period at the end of the entry that Illinois is rejecting it. I tried without the period, I tried with 00 after the period, I tried to remove the comma—TurboTax kept putting the period and comma in. Illinois kept rejecting both secondary and primary taxpayers but finally got it to work with only driver’s license.
