If you have the new Norton Security Premium edition it does include the Premier version of Norton Family. As you have the older 360 product, you may only have access to the Basic Family protection. You can see the difference in the two Family versions here https://family.norton.com/familysafety/basicpremium.fs
You can also download the product from that link.
Contacting Norton Support via chat can tell you if your 360 subscription will cover the full Family features. www.norton.com/chat
