First, go to Jobs & Ads and then Jobs, after that click "More Filters":

Click the dropdown for Status:

Tick "Closed jobs"

Result - Closed jobs now appear:
Please be aware:If you click on a job and get stuck on this screen:

That job was closed before it had reached the open status - when you close jobs before they're fully approved they cannot be accessed, (or opened).
Hope this helps!
