Hidding Search Box

I don't see how to hide/remove the search box on the header space. I'd like the header right sidebar image to match the size on the theme demo. https://catchthemes.com/demo/devotepress-pro/ (So far this new site is only on my local wamp). So please see the image here: https://livingskywildliferehabilitation.org/wp-content/uploads/2021/01/Searchbar.jpg
