Norton360デラックス３台目をWindowsに使いたい

In May 2020, I purchased the Norton 360 Deluxe 3rd Year 3rd Edition for smartphones and am using it for 2 smartphones (Android). I recently purchased a computer, so I'd like to insert the product key for the remaining one and use it, but I can't figure out how to do it. Does the address match the address and password of the first smartphone? On the screen that protects other devices, there is an email text copy link, but I don't know what to do from here. I'm really a beginner, so I would appreciate it if you could teach me in an easy-to-understand manner.
