Get your taxes done using TurboTax

@Kipa,  I agree with @babyrd55 about the "Tax Payments" worksheet for any quarterly payments you may have made.  Any dates that you enter into that form will carry through to the 2210 Penalty Worksheet.

 

In addition, and I think this is what is impacting your calculation, on the very top of Form 2210, line D, you can enter a date that you will be making your payment to the IRS.  If you don't enter a date, TT defaults to 4/15/22.  Changing that date will recalculate the number of days that you owe interest to the IRS.  (TT also asks the question of when you are going to be making the payment towards the end of the step by step interview process for underpayment penalties).
