Yoko: Adding Google Search under Page Navigation

Hello, I’m new. ??

I was wondering if anyone could help me add a Google Search (from AdSense) under the page navigation (top right of page) on my site. I already have the code for the Google Search box.

Ideally, it would be right justified just above the banner (and below the page navigation). I have no idea where in my code to tweak this.

My site is https://welovesoap.com

Your help is very much appreciated!
