I understand that you are trying to do your onboarding.
I am not sure if this is something that you are supposed to complete in Canvas or outside of the LMS.
If you are required to complete this in Canvas, you might have been added to a course shell to complete this. You can check by clicking on the Courses button and selecting the link for "All courses". If you don't see anything there, Your institution might want you to complete this outside of Canvas, from the student portal. You can always reach out to your specific institution and they can verify this with you.
