Change header siteurl on subdomain

So I’m not sure how to edit this code so that the Blog Title URL goes to my blog home and not the subdomain home.

<h1>/” title=”<?php bloginfo(‘name’);?>”><?php bloginfo(‘name’);?></h1>

The subdomain url is wuf.shlinklincolnsports.com. I want it to go to shlinklincolnsports.com.

Do I need to edit “siteurl” somewhere or is there an easy way to edit in the new URL in the code above?

Thanks in advance for your help.
