So I figured it out. Basically that email is a permanent alias of my account. I did not add it to my account like I thought I did. This was my reason for wanting to remove it. Somewhere down the line that became my official "@icloud.com" email which you can not change even if you wanted to.
Overall you can remove any alias that you add yourself, but an "@icloud.com" email that you make using that same account can never removed. If you use that same email address with another account, and add it yourself, people can find that account with that email or email the original account.
ℹ = @
because it thinks I am adding actual addresses
For example, lets say you were to make a new Apple ID with a gmail account as its Apple ID
"example123ℹgmail.com" would be the user ID
Lets say you have this new account but you want people to be able to find you with your old account
"toytruckℹgmail.com"
and on your old account you happened to also make an "@icloud.com" email address connected to that "toytruckℹgmail.com" Apple ID and you made that "hotdog1ℹicloud.com"
well you could essentially make/remove "toytruckℹgmail.com" OR "hotdog1ℹicloud.com" as aliases of the "example123ℹgmail.com" Apple ID.
Where you can run into a problem though is if you think you can remove the "hotdog1ℹicloud.com" alias from your old, "toytruckℹgmail.com" Apple ID Because you can't. Also you can't change the "@icloud.com" address according to and Apple representative I spoke to on the phone.
Thank you for trying to help me Drew. The reason why I came here for help was because I actually did not make the icloud address for my account so I wanted to get rid of it or change it atleast. Both things I can not do. Since neither are possible I will just ignore them.
