Oh, yeah, Salesforce deleted that tab a few weeks ago and we published a new version of the instructions and alerted instructors. But you must have the older version still. Let me know who your instructor is so I can make sure they get the updated one.
In the meantime, the way you can still create a new object is to click on Object Manager (upper left) and then you'll see a New button on the page that comes up. Just click New and then the rest of the instructions will work fine.
