What is a NJ1040 Overpayment?

The NJ 1040 Overpayment means that you overpaid NJ tax and will be receiving a refund. 

Please note, when you come to the question that asks if you want to apply your Overpayment to next year's taxes, you will select the the option that says you do not want to apply the refund. This will allow you to receive your State tax refund this year..

What if you selected yes to this question, but would now like to update the answer to no. I haven't completed filing so I still have the ability to update my NJ state return, but it's not updating my answer to this question from yes to no.
