Good morning, @ChrisC2 ...
I see you posted almost the same question on another topic located at: Viewing my course - Instructure Community (canvaslms.com).
In Canvas, try going to your "Courses" >> "All Courses" screen. Do you see your course listed on that page? If so, it will indicate if it is published or not published. Your instructor is the one who publishes the course for you and your classmates to access. On the "All Courses" screen, you should also be able to place a star next to any courses you want to "favorite". These starred courses will then show up on your Canvas dashboard for easy access. Here are a couple Guides for you to look at:
Keep in mind that, as the second Guide states in the light blue box, if you do not "favorite" any courses, then up to 20 courses will show on your Dashboard. As soon you place a star next to one or more courses on the "All Courses" screen, then only those courses will show up on your Dashboard.
If your course(s) aren't showing on the "All Courses" screen, please reach out to your school's Online Learning / eLearning / Distance Learning department. Someone there should be able to help you find where these courses are located...or how you can get access to them.
Hope this helps a bit!
