Where does the data go from an order form?

Question:
Where does the data go from an order form? For example, if I add custom fields to the check out order form, I don’t see them writing to the CMS section of the database

Product:
Wix Store Check Out Process

What are you trying to achieve:
Access the data from the form and use for reporting. i.e. Collecting household construct in the form, would later want to report on house hold counts.

What have you already tried:
Created a test order and looked for the data. Searched the forum.

Additional information:
None

Go to the order in the Orders tab to view what customers entered in custom fields.
