I'm just commenting to say that TagTeam is correct - the short-term rental with Material Participation goes on Schedule E, not Schedule C (unless you provide "services", such as maid service or meals).
You will need to use the CD/downloaded version to go into the "Forms" to indicate it is non-passive.
As for your question to amend to change applying Revenue Procedure 2022-69, I'm not sure. At first glance, I don't see any restrictions about doing that, but I haven't dug into things too deeply so I could be wrong. At this point, why do you want to amend, rather than just leaving it as it is?
