Site Description and Tagline in Google Search Results

Hi,

When I search for a term or my site’s name in Google, the first line under the site link is always the excerpt from my latest post. Instead of my latest post, I want it to display my site description.

Is there a setting in wordpress to do this?
I’m using Genesis with a child theme and the yoast SEO plugin.

I have provided the site description in all sections:

WP General settings: Title and description
yoast: Title and Meta
Theme settings: title and tagline

Thanks,
A
