Edit in what way? Is the birth date missing or is it wrong? Do you have a mobile pass or a paper pass? 

CanNOT do yourself-of course not-just think-anyone would buy a cheap youth pass and then change age?

IF you made a genuine mistake and can prove it with a pic of some ID then wait+hope+pray for assistacne-fill in the form for that and state very clearly when you think to travel-requests are trwated as far as possible to that order

I noticed my wife’s birth date had the wrong year and just need to correct that.  I submitted a request to them but waiting to hear back.

That's indeed the only way to get it corrected.
