Hi, I made an PlayStation Network account and my idiot brother was doing it with me and made my age something that wasn't true, and now I don't know how to change it! What can I do to change or atleast check the age on the account? I can't recover the account to my PlayStation without it!
You can't change the date-of-birth for a PSN account after the account is created. If you don't know that date-of-birth that was registered for the account, then you have to contact Playstation customer support by phone or live chat, during business hours, to recover the account (https://support.us.playstation.com/app/contact_options).
