Check your actual tax return. Does it show a refund? See if it's on another line to apply it to next year. There is a question at the end that says you have an overpayment and if you want to apply it. Did you see that one?
You might have told it to keep your refund and apply it as an estimated payment to next year. Did you file it yet? If not then go through the State tab again, probably near the end and look for that screen again to change it. Change it to No and delete the amount.
