I'm going to need Intuit to correct what these boxes mean. Military income is taxed very differently in various states. And apparently, in Proconnect, checking this box also means various things.

Example, Illinois does not tax military income. If you check this box and select IL from the dropdown, it recognizes this is IL Resident military income, and puts the amount correctly in the IL credit schedule to not tax the income. 

Nebraska DOES tax resident military income. As does Colorado. If you check this box on those returns and select the correct residency state, it incorrectly puts these wages into the schedule as "Non-Resident Military Wages" and doesn't calculate taxes on the wages, even though taxes are due.

99% of my clients are military families. This is killing me.
