I live in missouri. i am in the guard stationed in missouri. i have active duty pay. not combat pay. just title 10 active duty. where do i deduct it on my return?

Please ensure that after you entered your military W-2 that you check  "Active duty military - The wages on this W-2 are active duty military wages" on the "Do any of these uncommon situations apply to this W-2?" screen.

When you get to the State continue through the Missouri State questions until you get to the "Active Duty Pay Deduction" screen where you can enter the Active Duty Pay Deduction (see picture)
