Veronica, in your course, open course administration > users > enrolled users. As a teacher you should see all who are enrolled in your course. In the status column you will see something like this:
This semester, I have two enrollment methods, manual enrollment and LTI enrollment. When you move your cursor over the "i" (on the right side of active), you will see the enrollment method of the user.
With kind regards,
