Hi @dcsgolions,
Are you using the free-for-teacher Canvas instance, or one provided by a school/institution/organization which you're employed by? I ask because there could be significant differences to the procedures to add people. If free-for-teacher, if you created the course you should be able to add users via the people tool. In other instances, you'd likely need to talk to the local Canvas team to figure out how they have enrollments work. Oftentimes enrollments are automated from a student information system (sis), or there may be only specific people who have the ability to add users. It's very hard to say what the exact situation is for you because most of us in the community are just other users from around the world and have no access to your exact Canvas course or account details to offer more specific advice.
I hope this info is useful in some way though.
