Checkout page in 2 columns

Hello, I use your theme for my website, and I had issues with checkout page, in elementor I see it in one thin vertical line, on front end I can see it better, but not nice.

I managed to make it look better, but I can’t find template that you use for checkoutpage.

I would like to put billing info in left col-6 and payment methods to right col-6, can you please help me out.
