Where is the field to edit

In this image where it says "Natural Wellness For Dogs" I'd like to change that line.  But I cannot figure out where to go to do that.  I believe this is my homepage, but I can't seem to edit that line.

Any pointers appreciated.

Sorry I should have been more clear.   When I open that the text is not at all the same. 

I get an option for SEO Appearance and to edit the description that currently reads:
Explore the world of dog nutrition and pet health coaching for optimal canine health.  Discover the importance of fresh food diet, quality ingredients and supplements.   Learn how essential oils, herbs, and homeopathy provide a holistic approach and preventative care for your dog's well-being.  Dana Brigman | Dog Nutritionist

@danabrigman You're having a similar issue to another post I just answered. If you temporarily set another page to Home, you'd be able to access the field where this description text lives. But it isn't impacting anything as the Marketing "Site Desc" is being used.
