Owe the IRS, Form 1040-V Payment Voucher

I owe money this year, and I chose to use direct withdrawal from my bank account and set up a payment schedule when prompted by TurboTax. Then, at the end of the filing process I was told to print the 1040-V Payment Voucher and send that in the the IRS with my check. Should I send a check or wait for them to take the money out of my bank account? Definitely don't want to do both at the same time. Thanks!
