You are very confused. If you have been paying the 4 quarterly slips each year that Turbo Tax prints out those were prepayments towards the NEXT year's return, not the current tax due.
The current year tax due is always due the first April 15 after the year ends, not a whole year later. It is one 1040V voucher slip or by Direct Debit from your bank account. And not by payments throughout the year unless you set up an installment plan with the IRS.
The 1040ES slips are quarterly Estimated payments for the next year so you don't owe so much next time.
