How to EDIT the comment area remove content from PADDER

I need help changing the width of the comment area. I have the padder set to 190px right now because that's what it needs to be on the homepage for the sidebar.

For some reason the padder also controls the comments area... why IDK?

How can I control the comment area so it's not squished into this 190px of the padder, where do I go to control the comment area and give it, it's own class?

Image attached.

THANKS!
