How do I move the navigation out of the custom logo area of the Product Theme?

Please see

The navigation is covering the custom logo. I have set up a child theme and have it activated. To make the necessary CSS edit, which Child CSS file needs to have the @import and selector in. Also is the @import line necessary, there is some question if the function.php now handles that. Mainly I need to clear up some confusion as to the CSS files that are involved to make the changes.
