Genre has to do with the content of what you write, not the age level for which you write. For example, I could write a sci-fi murder mystery romance for middle grade, or for YA, or for adults. The age group does not affect my genre (except that I probably won’t add a sex scene in the MG version, obvs).
I know you don’t write magical realism. Okay, I’m 99.9% sure. And how do I know this, you ask as you pound your desk in consternation and insist that I am wrong and that OF COURSE you write magical realism?
