Retirement tax questions

I am now a bit confused...Opus previous said I do not need to report the 1200 excess contribution just the gain that it made.  But if I understand your guidance, you are stating that I should put 1200 in the box 1 and the gain/earning it made in box 2a and use the the code PJ? Did I understand that correctly and then use the special instructions to answer the "which year...?" question?  Vanguard made two separate transaction for each me and my spouse.  We each had a one transaction/distribution for 1200, this was the excess due to being over the AGI  limit. And then we each had another transaction/distribution for gain/earning that 1200 made in 2023.  So, does this mean what Opus said about is not acceptable? Just forget about the 1200 and treat it like it didn't happen and only report the gain on a made up 1099R. Or is your advice the more appropriate way to handle.  Just confused now.  I see the logic in both.  Thank you.
