Visiting The Google Adsense Help Center was no help at all so I searched on Wealthy Affiliate and found wonderful tutorials for the next phase of Adsense (how to add the code for an Add Unit). This training by Belinda @bellabs12 is the most popular:
How To Easily Add Google AdSense To Your Website in 4 Steps!

So I did some more digging via google search and finally found some training on YouTube that taught 2 simple ways to add the code. Here they are:
2 Simple Ways to Add Google Adsense Verification Code to WordPress
1. Using a Plug-in called "Insert Headers and Footers"
2. Adding the code manually via Site Editor (almost exactly the steps I followed but with one simple twist)
In the Next Lesson You'll find the Precise Steps to Follow... if you're as un-techy as I am. :)
