Good morning, @ckyancey 
Welcome to the Canvas Community. Thank you for posting your question. If you only want to import assignments from one course to another, then you can follow the information in How do I select specific content as part of a course import?. As you follow along with this Guide, you will want to be logged into the course where the content will be copied to (not where the content currently resides). I like to refer to these as your "source" (where the content lives) and "destination" (where the content is going to) courses. A portion of this tutorial video might also help as you are working through this process: .
I hope this information will be of help to you, Deborah. Sing out if you have any additional questions about this...thanks!
