Deductions & credits

thank you for your answer, but I'm confused about step 9 in your reply.

I contributed to the Roth IRA last week so it's March 2024 and would request the recharacterization soon in March 2024.  If I will not receive a 1099-R for 2023, what should I do when filing for 2023 in your step 9, i.e. what amount to put in for "plus $xxx.xx earnings (or loss) were recharacterized"?
