I efiled a federal return 10 days prior to the entered debit date for the balance due. Return was successfully acknowledged. Debit for the state balance took place on scheduled date.  Federal debit date has come and gone now by 5 days.  Is a delay normal ?  Checked with bank and they see no action where IRS attempted to take money.  Should be concerned?  If so, where to start ?

Thanks for any insights!
