Shipping Layout help on check out

Hi all, I seem to be having a problem with the layout of my shipping options when it comes to the checkout stage.

Currently my Shipping/Checkout looks like this! However the problem is with tag connected to the price, because of the template the price is using a <p> tag which is too wide is stopping the options displayed correctly. I wish to find which PHP file has that connect <p> tag to the price and delete it in order to display correctly. Any help would be greatly appreciated!

all I get is a blank page after clicking the checkout button
