I spoke with the IRS.  The returns are "not fully processed yet".  They told me they are working first on returns that have refunds.  They also told me that returns with refundable credits are being manually checked for accuracy.  They also told me that is the return had a "pay by 4/12" date that they will honor that date as payment date even if they withdraw the funds at a later date.  They DID NOT guarantee that the funds would be withdrawn.  Told me to have the client watch their bank account.  What the heck??
