Retirement tax questions

Fanfare, does the fact that the 5329 goes with the tax year we missed mean we have to file an amended return, or rather because we didn't actually take a distribution in 2021 as we should have mean there's nothing to amend?  If the latter, then I'm assuming we take the missed distribution in 2022 (along with year 1 of my wife's RMD obligation for 2022) and fix it all then.  Which means we'd request the tax waiver for the 2021 missed RMD due to lack of clarity and guidance by the IRS, correct?
