Hi,
The shipping address area will appear automatically unless you deactivated it purposefully, or your products don't need shipping.
For a product to require shipping, it needs to have a weight, or the "Force shipping for virtual / weightless items" setting needs to be turned on in the HikaShop configuration:

If you want to add a field for adding a note, you want to create a custom field of the table "order" and of the type "textarea" via the menu Display>Custom fields.
