It doesn't sound like you properly scheduled your direct debit, if that's what you intended in order to pay your federal tax liability. You can review the option you selected by using the information below. Check to make sure you entered the correct banking information, as well as the date you chose to have your account debited.

Since your federal tax liability hasn't been debited, you can make a payment by using the IRS "Direct Pay" option, which would be the most expedient way to make your payment. I've linked that option below. If you're late in paying your liability, you'll receive some kind of notice from the IRS assessing a late payment penalty.
