I received a CP14 notice from the IRS for an amount due, that was direct debited from my account when I filed. Why did I receive this notice?

If you paid your tax bill but the IRS still sent you a CP14 notice, please be aware that due to their backlog, they may not have registered your proof of payment yet and you might receive a second notice. Also, make sure funds remain available and don’t cancel any check you sent.

Please see the TurboTax FAQ below for more information:

Ok, thanks for the info.  The payment that was sent to them was an ACH, directly from my bank account when I completed my taxes.  Funny you should mention their backlog, as I just received the notice a few days ago, but it was dated November 23rd, with a due date of December 14th.

Hey so what did you after you got the Cp14 notice? Same situation here. Not sure what to do as I tried to called many time but couldn’t reach a real person. Did yours get resolved?
