The Form 1099-R from the IRA custodian will just show a normal distribution with code 7. It will not specify the distribution as being a QCD, you'll do that when you enter the From 1099-R as described by Opus 17.
(The assumption here is that the QCD made "a few days later" was done in 2022 and not early in 2023. If the QCD was done in 2023, it will be reportable on your 2023 tax return.)
