So I see that Unearthed Arcana is on here and the mystic (psionic class) is SUPPOSED to be there yet I can't find it in the class guide can someone direct me to this
It does say that. It is wrong (I have also raised this issue). You can't create homebrew base classes yet (distant planned feature). Best you can do is try to jury rig it into a sorcerer subclass.

I can direct you to this (https://www.dndbeyond.com/forums/dungeons-dragons-discussion/unearthed-arcana/14259-unearthed-arcana-content-on-d-d-beyond). Sadly, it is not as good.
It says we can make our own how?
