My husband is active duty military but TurboTax is flagging our military income on Schedule M and won't let me efile. It's the exact same number on our Federal.

We have been filing both federal and state for years without issue and I am getting an error saying that military pay doesn't qualify for a military pay deduction on IL return, Schedule M.  I checked all my previous returns and TurboTax filled out our state returns exactly as they're filled out now and our tax situation hasn't changed.
