How to change the date used to calculate underpayment penalty?

I originally put a filing date of 4/15/2025 in as a placeholder. I believe this date is used to calculate underpayment of estimated taxes. Now I want to file earlier, like march 15, and I want to update the filing date, but I cant. if I edit the underpayment penalty section in Your uncommon tax situations, It only shows me the penalty that has already been calculated based on 4/15 but won't allow me to update the filing date to lower the penalty. :(

Is there a way?
