2210 penalty calculation for 2019

[jfgcpa8583]

Can anyone explain how the 2210 penalty worksheet calculates underpayment of estimated taxes works when using the annualized method? Very confusing layout with no explanation. Proseries software being used for 2019.

The penalty is based on what did not get paid for the period's due date: "The penalty is figured separately for each installment due date. Therefore, you may owe the penalty for an earlier due date even if you paid enough tax later to make up the underpayment. This is true even if you’re due a refund when you file your tax return."

I agree, the layout feels clunky to me as well.
