Cant get WP to integrate correctly

Hello All,

I recently followed this tutorial on integrating WP into my existing website template. (https://www.rivergraphics.net/resources-tutorials/how-to-integrate-a-wordpress-blog-into-your-existing-website/)

Here is my final results.. https://justinledelson.com/wordpress/

You can compare that to: https://justinledelson.com/about.html

What I wanted is for my new posts to go where the main content is and my side bar to go where my recent news is. If anyone could help me do this I would greatly appreciate it.
