How do I set or change the electronic withdrawal date of a payment?

Agent Information: The payment wizard uses the in the e-file code.  This is the date the payment will actually be withdrawn from the account and is either the default date due for that quarter or the override the customer entered.  Even if the client transmits today, the payment processing date will be the date in the e-file.

Comment:  I think that means the date in the e-file is 9/16.

Comment:  California payment dates can be overridden.  I don't see a place to override Federal ES payment dates.
