Thanks for posting your question. Unfortunately, the vast majority of Community members won't be able to help you find your English 124 course. We only have access to our own Canvas environments, and we wouldn't have access to your school's Canvas environment or your course(s) in question. The best route for you to take is to reach out directly to someone at your school such as your instructor (if you know who that is), your school's local Canvas administrator, or someone from your school's Online Learning/eLearning department. One of these folks should be able to help you find your course.
Also, it's always a good idea when you are logged in to Canvas, to check your "Courses" >> "All Courses" screen. How do I view all my Canvas courses as a student? - Canvas Community Do you see your course listed there? If you see it listed on the "All Courses" screen, but it is not published yet, that means your instructor has not yet made the content available to you and your classmates. If you do not see your course listed at all, then you will need to reach out to someone at your school.
I hope this will be of some help to you. Sing out if you have any other questions about this...good luck! Be well.
