How do I deal with a state tax adjustment calculated by turbo tax?

[xmasbaby0]

Deal with how?  And what do you mean?  Did the state change your refund?

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.?

New York adjusted a school tax credit (rate reduction amount) that was calculated by turbo tax .  This resulted in additional tax due.

TurboTax does not receive any information from the IRS or your state after your return was filed, so no one at TurboTax knows about a letter you received from the IRS or the state.
