Remove tags and add link to authors page

Hello! I hope you can help me with this issue as you have so many times in the past.

I am developing my second WordPress site. On the first site, I was able to easily add a tag to link the author byline to the author’s bio page, and also to remove the tag list at the end of the article. But on the new site, I am having issues because it seems like all the information that contains thatinformation is located in a single tag and I am unable to edit it. Of course, I am obviously inexperienced when it comes to editing templates.

How do I remove the tag listing at the end of the article and make the author byline a live link to the author.php page?

My site is located at:
