Hello there, @lori_mitchell1 ...
Please follow the steps in this Guide: How do I add users to a course?. Take note of the information at the top of the page within the blue box...as you may not be able to enroll instructors on your own depending on what your school's local Canvas administrators have set for permissions. If that's the case, you'll need to reach out to those folks to help you with this.
I hope this helps, Lori. Sing out if you have any questions. Stay safe, and be well.
