No H1 tag in my blog posts. How automatically add to all blog posts?

I see that there is no H1 tag in my blog posts which surprised me.
I thought my Title would automatically have H1 tag but that is not the case.

What can I do to have H1 tag wrap around my Title automatically for all my blog posts so I don’t have to manually add H1 tag every time I create a blog post. I have a lot of blog posts that I would have to manually add.

here is example of blog post on my website. I did search source code and found no H1 tags

I also found this in CSS code added a long time ago and not sure why its there. I took it out and it still shows no H1 tage in blog posts

#hb-page-title h1 { display: none; }
