IRS recalculated 2023 taxes and sent refund + where to enter

Hello,

In May 2024 IRS notified me they made a change to 2023 form 1040, and refunded an underpayment penalty of $306.This was reduced because of a presidentially declared disaster area.  Where do I enter that on the 2024 taxes?

 

Thank you very much,

 

Iris
