Blog posts disappeared from page after renaming Front Page

Hi,
I’m brand new to WordPress.org and using SiteGround hosting service. SiteGround transferred my blog content from WordPress.com (free version) to my new domain at leikeladesign.com. The blog became my front page. I wanted the front page to be my portfolio and other content and I wanted to move my blog to a different page called Blog in the navigation menu.

What I did was I renamed the front page “Portfolio” and now my blog posts are not viewable on my website. I am able to access each of the posts from the Posts area on the Admin site as they are all archived under directories for their respective posting months. How do I reestablish a blog page on my website with all of my blog content to be viewable and searchable by visitors to my site?

P.S. I’m currently using the Twenty Seventeen template.

Thank you,
Leikela
