Probably a silly question, but trouble shooting generally starts simple - there are two major steps to creating your listing: you populate the content (text, pictures, etc.) and then you actually have to list it. When you're viewing the listing, somewhere is a drop down that shows if your listing is "listed," "inactive," or something else, maybe "snoozed." You'll want to confirm that, in addition to having created it, you've also actually "listed" it (this seems to be Airbnb's terminology for publishing your listing).
Hopefully that helps! Best of luck.
