State tax filing

I lived in KCMO for 5 years and used Turbotax every year and it never once told me I need to pay this tax (employer was not in KC so didn't withhold). After moving I just received a collection notice saying I owe back taxes plus interest plus late fee. I have friends who use TaxAct and were informed of the tax. I feel this is an error on TurboTax's part: what will TurboTax do to remedy this issue so I don't have to pay the extra fees?
