@MojganBanaee ...
You're going to need to reach out to your school to ask specifics about your 121 course within Canvas (not convas). Unfortunately, almost all of us here in the Canvas Community website do not have access to your school's Canvas environment or any of the courses at your school to help you find what you are looking for. I'd suggest reaching out to your school's Online Learning / eLearning / Distance Learning team, or you might even try contacting their Registration department. Hopefully you'll be able to find someone at your school who will be able to help you locate your course.
Also, just to be sure...you might want to try looking at your "Courses" >> "All Courses" screen within Canvas. You may see the course listed there, but it might have a status of not published. If that is the case, your instructor hasn't published the course yet to make it available to you and your classmates.
Good luck. I hope you'll be able to connect with someone at your school soon!
