How to Make Separate Payments for Balance Due and Underpayment Penalty at Different Times on TurboTax

I need to split my payments because I owe a large amount to the IRS and need time to gather the funds. However, the underpayment penalty is much smaller, and I don’t want it to keep accruing interest. I’d like to pay the penalty now and the remaining balance a month later (right before 4/15/2025).

 

Which option in Turbotax Online should I select in the screenshot I attached to make these payments separately at different times?
