This is a strange request. Do you know that renewal is automatic and will be charged to the same credit card?
Did you buy individual licences or Teams or Enterprise licences?
With a Teams or Enterprise licence, you will see the number of licences by going to your admin console: https://adminconsole.adobe.com (you need to be an administrator for doing that).
The first page will give you a summary of your licences.
With individual licences, this is a little tricky, as each licence has its sign in attached. You will need to contact Adobe, and I do not know if Adobe can find the required data by reverse searching your credit card.
An alternative solution is to look at the credit card charge.
