What if you don't remember your ex-manager's last name?

I'm applying for a few jobs, and of course they ask for references. However, I don't remember my ex-manager's last name or any of the other supervisors' last names. We would just call them by their first names...

I left the job a little over a year ago, so it's not something fresh in my mind. Do I make up a fake last name?

I tried to move on without providing the manager's last name [ it's an app for Petsmart ], and it wouldn't let me continue.
