RMD

This is my first year for doing RMDs and having multiple IRAs, I did my withdrawals in Sept. 2021 to avoid doing it twice in 2022. Unfortunately, one very small RMD fell through the crack and I just did that withdrawal today (March 21). Since the first RMD is technically not due until April 1, 2022, I think this is not a problem. But my question is, how do I report the March RMD to the IRS in TurboTax since I will not have a 1099-R?
