How do I input IRA early withdrawal Substantially Equal Periodic Payments (SEPP) if my 1099-R shows Code 1 (no exception) and not Code 2 (with exception - SEPP) in Box 7?

I was 57 years old in 2024; I completed form 72T to begin taking SEPP in October 2024; I am looking to ensure I report properly and avoid 10% early withdrawal penalty.
