Editing template

I’m new to WordPress and have been learning how to update a site in WordPress and got the basics of it all figured out, but I’m stuck on what file I need to edit and how I should edit it in order to change part of my template.
On the home page there is a section which has 3 blog posts which are 2 lines from the blog post and they are clickable to the blog page, I don’t want the blog posts there, I want to list 3 text statements instead, so i thought i’d just list the statments as individual blog posts and that’s fine but they are clickable, which I don’t want.
So I either need to be able to make them unlinked, so they look like statements/text only, OR ideally remove the Posts section from the theme, on the home page, and replace it with just a text box.
I have no idea how to do either of those.
Is there an easy way for a beginner to do this?
Thanks very much for any guidance.
