Hi there, @hsoccerock ...
First, click on your "Home" page, and then look at the URL for your course. Take note of the Course ID number in the URL.
Example: https://SchoolName.instructure.com/courses/123456
Next, go to your "Settings" page, and then click on the "Import Course Content" link on the right side of your screen. (This is where you would have copied course content). Under the "Current Jobs" heading, hover your mouse over the link for the most recent course copy, and then look at the bottom of your web browser. You should see the URL of that link displayed. Does the number in that URL match the Course ID number in your course URL at the top of your screen? If so, that means you were trying to copy course content into the same course you were already logged in to.
You said, "...when I go to the period where it was supposed to be copied to it isn't there". In order to use the Course Import Tool, you need to be logged in to the course where the content will be copied to. I like to think of this as the "destination" course. When you are in this course, you will be selecting the course where the content currently lives. I like to think of this as the "source" course. Once you tell Canvas to import the content from the "source" course to the "destination" course, then that content will appear in the course for you.
How do I copy content from another Canvas course using the Course Import tool?
I hope this helps to explain how this all works. Let Community members know if you have any other questions about this...thanks!
