By default, PTO refunds the entire overpayment. In other words, there is nothing to force.
The screen that you and George referred to is applicable when you want a portion of or the entire overpayment applied to 2020 ES-tax. If you have entered anything on that screen on the line for Apply overpayment to 2020, remove them and the overpayment will be refunded in full.
Still an AllStar
