Balance Update
Found at:
The likely reason for not seeing the "Current credit card balance" option is that the user has setup the Reminder to be recorded directly in the credit card account: when that is the case, Quicken will not offer the "Current credit card balance" option.
The Reminder should be set to record the credit card payment transaction in the Quicken account from which the payment will be made (with the category of that Reminder being the name of the Quicken credit card account in square brackets).
