1099-R with Distribution code P - how to amend previous year?

We over-contributed to a 401k in 2022, and in 2023 we received a 1099-R with distribution code P.  Turbotax 2023 is telling me that I need to amend the 2022 return.

 

Where, exactly, to I put in the information in the 2022 amended return?

 

Thanks!
