@SophiaOstergren ...
You'll probably want to have a conversation with your school's Online Learning / eLearning / Distance Learning team to see if one or more courses on your Canvas "All Courses" screen can be deleted or not. Each school that uses Canvas as their LMS (Learning Management System) handles this differently, so I wouldn't want to speak on your school's behalf as to how they handle this kind of request. On the University of Minnesota's website, I found the following login page for Canvas:
Web Login Service (umn.edu)
There is a link on this page for "Technology Help". I'd recommend starting there to see if you can get some assistance...or at least maybe they can guide you to the correct person(s) to help you with your Canvas course(s).
Good luck to you!
