You have to ask the state. TurboTax gets no information from the IRS or your state after you file your tax return. If the state changed your refund, they should have sent you a letter to explain.

MY STATE REFUND WAS LESS THAN I EXPECTED
The state will send you a letter explaining the change. TurboTax does not get any feedback from your state after your return is accepted, so no one at TT knows why your state refund was less. Did you owe back taxes, child support, or student loans? Traffic fines, etc.?
