I paid to have my states taxes (OK & MO) filed. My W2 was in the system so didn't have to enter it. Now I see the amounts of withholding on my returns don't match the W2.

I received a letter from the Oklahoma Tax Commission stating instead of a refund of $738, I owe $666. I was told to send in my W-2s. I was making copies of them today and realized the amount of withholding on both my Oklahoma return and my Missouri return do not match my W-2s. I will now have to file amended returns for both states. Can I get a refund from Turbo Tax for what I paid for them to do my state returns, since they are wrong?
