Hello @KERIMILLER
I understand you have a question about locating your sandbox. Typically a newly created sandbox will appear on your dashboard as an Unpublished course.
You can sometimes locate it in your "all courses" list. To access that, you would click on the "Courses" button to the left of the screen and select "All courses."
HERE is a guide on how to look at all your courses.
Hopefully this helps!
