TechAdam on "[Theme: Travel Blogger] Layout different using child theme"

I am running version 1.4 of this theme. I want to update the theme but not lose my changes. I have created, as far as I can tell, the necessary folder and file to have a child theme. When I activate the child theme, all of my content, including my right sidebar content, is in a left sidebar. I have no left sidebar configured/visible/etc. Below is the code from the style.css in my child theme directory:

/*
Theme Name:     travel-blogger-Child
Description:
Author:         Adam
Template:       travel-blogger

(optional values you can add: Theme URI, Author URI, Version)
*/

@import url("../travel-blogger/style.css");

From what I have read, that would basically make my child theme exactly like the parent theme, but it's not.
