Get your taxes done using TurboTax

I did receive state refund (MD) for 2016. I had 4 W2's for 2016, added column 17 of all 4 W2's  (All were for MD state) and also checked itemized deductions. I am guessing the state refund to be taxable income but the state refund is not shown as income on line 10. The adjusted gross income (line 37) has no impact of state refunds. Am I doing something wrong?
