H1 being inserted into my site

I have a custom theme and when I installed wordpress SEO it inserted an h1 tag near the top of my page. I want to remove this because it doesn’t fit into the theme. I have another h1 that will fill the needs of this one anyway.

I can share the link if necessary. Please let me know how I can remove this.
