Go to the listings tab and click the listing. Click the settings icon in the top right corner. The last settings option is Remove Listing.
It's against Airbnb's policies to remove a listing and to then create a new listing for the same property. If you'd like to pause the listing, rather choose the 1st option under settings to temporarily unlist the property.
It was for a listing that I had never really used it was out in years ago never had a booking as I don't think I set it up right .I also never corrected it as I found it wasn't right at that time to become a host.
I've since moved and I am now in a position to go forwards with becoming a host .
