So it's my option to pay with vouchers or just let the whole amount come out??? Didn't really understand your response sorry

The taxes owed on your 2016 tax return must be paid on or before April, 18, 2017.  If you chose direct debit from your bank account for payment on 4/18/17 then the IRS will debit your account on that date for the 2016 taxes owed.
The Form 1040-ES that were included with your tax return were based on your taxes owed for 2016.  The forms are used to pay estimated taxes on the 2017 taxes.
