All of your inventory items are saved in the Products and services window, cbrennan1.
This is the main hub where you find and manage all item types, such as inventories, non-inventories, and service items.
Just go to the Gear icon and select Products and services. Then, choose Inventory under the filter for Type so you can only see inventory items in the list.
