IRS 1099-G for 2020, box 2 for Interest Paid on Tax Refund. Where to enter it?

Hello!  I am doing my son's 2023 taxes and he has a 1099-G/1099-INT from 2020 we received from the IRS.  The form says it TAKES THE PLACE of 1099-G/1099-INT.  Box 1 is empty and there is an amount in Box 2 for Interest Paid on Tax Refund.  I cannot find where to enter this.  When I follow other's input from here, it says to go to the form, but the form doesn't clearly answer where to put it either.  

 

Thanks!
