Your Zoom account's Recordings section will show you both the Cloud Recordings you have done, as well as a list of all of the Local Recordings you have done. Cloud Recordings can be fully managed through this section of your account, while the Local Recordings will only show you what you've recorded, and where to find it on your local device(s).
To find both of these sections, please first start by going to your account. General information on logging in to the website dashboard is found here.
The direct path to your Recordings can also be accessed here and log in as necessary.

You will have to go to that computer and manually remove it yourself. Luckily the Local Recordings list has both the Computer Name and the Locations columns that will show you which Computer to look at, and in what directory those files will be. Clicking the Delete button will give you the following prompt:
