How to upload my logo using wp and cherry2.2.1

Word press newbie my site is https://www.insightgolfadventures.com. I have my logo uploaded to my media library (in what I think is an appropriate size) and have tried to follow directions to upload it. I am hitting a road block with finding the “header file” to open and place it on the page. It is visible in the Theme Logo window and has a url associated with it (https://insightgolfadventures.com/wp-content/uploads/2013/08/insight_golf-adventures-e1377818973213.png). Where am I going wrong??
