Identify the devices for my used licenses

guys, i was just reviewing the norton website because my renewal is upcoming. when i reviewed the licenses that are being used, i was able to identify 2 of the 3 devices. i am pretty sure that the third is for a computer i no longer have but i want to make sure before i delete the license. is there any way the website can give me more information about the device that this particular license is for. any assistance will be greatly appreciated.
