Thank you for your business first of all. Great question too. To turn the page you’ve created into your blog page, go to the settings section of your WordPress dashboard and click on reading.
At the top of this screen you select what your front page displays. Right next to where your front page is selected, you’ll see a drop down menu to select the posts page. This is where to select the page you’ve made for your blog. Update your settings and that page should now be your blog.
