I usually get a refund from state, this year I owe, did the law change or did I do something wrong?

The changes made to the federal & state withholdings will take effect when you file your 2018 taxes next year, so what I would suggest is to check the status of your state refund @ the web link below and see if there was a misunderstanding or mistake.
