There are few reasons to retract an offer
Go to the offer and the information should be there
You can be reported for invalid retractions
Offers are good for 48 hours or the end of the listing whichever comes first

You seem to have the wrong idea on how to use ebay as you have 3 bid retractions already on your account
You only bid or offer if you are sure you want the item
Bidding or offering and then retracting wrecks a sellers listing and could cost them money
