Hello @shari_bowers 

I understand that another teacher made you a TA in her course and you are curious how you can access the course.  

When you are added to another Canvas course with a TA or Instructor role, you will receive an invite through the Canvas dashboard and your email. When you log into Canvas, the invite will be on your dashboard, at the top of the screen. Once you see the invite, you can click on the Accept button and from there you will be able to access the course from the dashboard and All Courses list.  

If you have not received the invite, you might want to double check with the instructor who tried to add you to the course. I have seen some cases where the instructor has added a TA to a course with an incorrect email address. You can double check your email address that is in use within Canvas by clicking on the Account button and selecting Settings. Your email address will be listed to the right under Ways To Contact. 

Hopefully this helps!
