An overpayment is your refund. You can have them keep all or part of your refund as an estimated payment towards next year's tax return. But most people want to get their refund now. So to get your refund now pick do not apply it to next year.
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.
