help me get my steam account from EA mail which I don't have data

Hello, I recently bought BATTLEFILD 2042 on my Steam account, when I entered the game I received a message that We sent a confirmation code to the mail iv*****@gmail.com. I don’t know what kind of mail this is and why it is associated with my Steam account, how can I solve this problem I just don’t have any data about this mail

I am from Russia and I can't figure out how to contact support, please help, if anything, my discord is spaceandbruh, I am ready to communicate in English
