Hi Judy, I found this really great article where someone asked the same question. It's filled with useful information about the cottonwood and what you can do about the roots. Best of luck
If you want to trim back tree roots you can safely prune roots which are 3-5 times the diameter from tree. With that being, if your tree has a diameter of 3 feet, only cut tree roots 9-15 feet away from the tree. Ensure to mark the area which you will. Then dig a hole up until the root is completely exposed.
Here's how to do this, Step #4 is especially important:

I would consult an arborist for the best advice.
Definitely reach out to an arborist for this as you don't want to inadvertently kill the tree. You can contact your local garden center and they should have people to refer you to.
