@ppalmer Welcome to the Canvas Community! We're delighted to have you here. tross is correct; the members of this Community don't have access to your account and can only give you general guidance. If you're brand-new to Canvas and haven't yet selected any courses as favorites on your Dashboard, the newly-imported courses should appear as course cards on the Dashboard. However, if you have previously chosen favorites, you might find the courses you're looking for by clicking on Courses in the left (global) navigation and then on All Courses. https://community.canvaslms.com/docs/DOC-10184 provides detailed instructions.
And if if you don't find them there, by all means reach out to your school's help desk.
