I have the same problem with my own tax return, debit for estimated tax scheduled for 4/15 through Pro Series Basic has not occurred as of today 4/21. Return was Accepted by IRS 4/4. The bank info is all accurate.

In addition, one of my clients contacted me today that her balance due debit scheduled for 4/16 has not occurred yet as of 4/21.  Her bank info is correct and a different bank than mine.

I've been on hold with the IRS number for 45 minutes now.  Have regularly scheduled direct debits and never had a problem until this year.
