Customizing the footer

In the Oshine theme, the footer settings only gives me an option for three or four columns? I want something simple. Just one column.

I created my own in the Tatsu Editor. Figured I could turn off the footer and copy/paste code for that part to put under each page so I don’t have to duplicate my efforts. I don’t have any coding background but I can see where coding for that section starts.

I tried and my copyright comes in as inline text. Center alignment falls off. Underneath are my FB, Instagram and LinkedIn widgets but the hover, border colors etc are off.

All I want is this part centered:
