Center woocommerce shortcode in homepage section

I’m using the woocommerce plugin with this theme, and we only sell 1 product.
In the woocommerce home page section, I’m using the products shortcode, but because we only have 1 product, I want to center the product in the middle of the section. Right now it lists all products so our only product is at the far left with a big space on the right.

How can I do this? I tried using margin: 20px 20px 20px 500px manually in the shortcode box, and it works for desktop but will push the element too far for mobile so it won’t be visible.

Please help.
