links being carried down to unrelated content

My website was set-up by a outside company and I sometimes try and make simple coding changes to it. I added some content to my home page describe below.

Heading
link to outside source

Heading
link to outside source

Heading
link to outside source

The problem is the link is being carried down to the heading below it when I don’t want it to be since they are unrealted. How do I fix this? https://www.tentalentscpa.com
