Where do I edit the author website URL?

Hey guys, I need your help with an issue I'm facing on my Squarespace site. I've recorded a Loom explaining the problem and showing the code where it's located. Could you please take a look at it? Here's the Loom:

The code I need to edit 

<a href="http://www.ralphkerlesart.com" class="author-website" target="_blank">http://www.ralphkerlesart.com</a>

Have a read of this link:
