Allow shipping address form to appear on checkout page while shipping options is disabled in settings. Woocommerce

I am using wordpress and woocommerce for a shopping website. When shipping is enabled through the settings of the back office, an option to enter a shipping address is displayed on the checkout page. However, to get the shipping to work properly for my products, I had to disable the shipping option and use a plugin called product add on, but since shipping is disabled, the shipping address form goes away. I need it back! * force shipping address option form onto checkout page when shipping option is disabled in settings * make sure the tax is still being calculated when being shipped to MO, I believe this is working properly but can't be sure until the shipping form is added. Thanks for looking. MAX 3 Days but sooner is better!
