I have apparently miss-categorized my item. How can I stop the listing and start over?

How can I completely clear my listing and start over?  (one item).

Go to your Seller Hub-> Listings

Go to -> End Item.

The item will now be in your Unsold Items

Go to-> Sell Similar

Make corrections and list.

If the listing has more than 12 hours left then you can just revise it to change the category (unless it's an auction that has received a bid).
