I didnt get my state with holdings entered correct and i already filed. what can i do to fix this?

To fix your State withholdings, you will need to wait until your tax returns have been Accepted or Rejected. If Accepted you can log in and Amend. If Rejected, you can log in and Fix any areas that need to be fixed, added, or removed. 

It's possible that the state will catch this on its own and adjust accordingly.   However, if you are itemizing for Federal, your Federal Schedule A will be wrong.
