Copyright with music created on garage band and monetized YouTube videos

What is the status of dealing with copyright claims on music created in GarageBand that is used in YouTube videos. I want to create music in GarageBand for my YouTube monetized videos but I don’t want to get hit with a copyright claim on some music that I created with loops and such in GarageBand.

How do I deal with those claims if/when they come? Who do I contact and how do I reach out to them?

The last I heard people were dealing with this issue was 2022. I am wondering if it has been straightened out yet.

If GarageBand is not a reliably safe place to make your own music, what software is best (but still simple to use like GarageBand)?

Also, what about attribution issues with music created in GarageBand? How do I do that for YouTube videos?
