Trying to place social media buttons centered in footer

Hi everyone,
Forgive me I’m a little new at this.

I’m trying to place social media buttons at the footer of the theme and having problems. I’ve tried a widget to keep the buttons/links centered on the page and that didn’t seem to work, so I placed images of each icon in the middle section of the footer. But as you can see, they’re not really centered and I’m just out of ideas on how to make this look good on every page.

Here’s the site https://jkatrell.com
Any suggestions would be helpful.
Thanks so much,
K
