After you file

I even contacted TURBOTAX SUPPORT who said i could file an ammended return to update your direct deposit information.  From what my accountant said is that you can't file an amendend return just to update your direct deposit.  Turbotax doesn't provide online ammended returns either...those are requried to be done manually...so my gut is telling me that there is NO WAY to update your direct deposit infromation, if you have already filed.  I am hoping I am wrong, but right now i don't believe so.
