Please explain why in June of 1828 Joseph Smith was taking membership classes to join the local Methodist church [if it was part of the heritage of "schismatic Catholics"]...
You’re fun and funny. How should I know?
But the Reformation is a known schism from the Catholic Church. That’s undisputed history:

What were they breaking away from, if not the Catholic Church. Furthermore, the Protestant Reformers didn’t reject the entire doctrine just bits and pieces. That makes them schismatic Catholics.
It’s obvious, no? So the Reformation is simply an attempt to “reform” Catholicism into a religion more palatable to some. Instead of going back to the Bible with pure intent and open minds, they chose and picked like you would at a smorgasbord, swallowing some doctrine whole and rejecting others.
