Oddly, I had the same issue on a client on Feb 24, 2020.  In that case the letter said the IRS rejected the payment.  Made no sense.  I just now reprinted the acceptance letter, out of curiousity, and it does not say the payment was rejected, but it also does not say the payment will be withdrawn from the account.  The State information does make that statement.

On a second client the same today - no confirmation that direct withdrawal will occur, just that there is an $xxx balance due.  How do we rely on this, to know the direct withdrawal/debit will occur?!?!?!
