Without examining
your return (we can't see it in this forum), it's impossible to say exactly
what caused you to owe state taxes. However, there's
a high probability that at least one reason is listed in the FAQ below. I
recommend printing
your 2015 and 2016 state returns and comparing them line by line to see what
changed.
Also, you may want to look at adjusting your withholding
by submitting an edited W-4 (Employee's Withholding Allowance Certificate).
