State tax filing
You only have to pay tax on the income you earned while living/working in Missouri. Since your other state doesn't have an income tax, you won't have to file a return for that state. You have to tell the program you were a part year resident. You also have to tell the program how much of your income you earned while a Missouri resident. You make this allocation on one of the screens in the Missouri state tax section. See screen shot below:
