Need to make author name clickable on post

Hi,

I have the author name visible on top of the post, but it displays as plain text, so it doesn’t link to anything. I’d like the author name to link to a page.

I see other people have resolved issues where the author name is linking to their home page, but on my website the author name isn’t even a hyperlink.
I am using a child theme for Genesis.

Thank you!
