If you owe tax, you need to pay it by the 04/18/2016. You can choose direct debit, and you can choose the date for the tax to be debited from your account. If you give a date before the due date, the amount due will be withdrawn on that date. There's nothing similar to WMR for payments.
You can also print out a voucher, Form 1040-V, in TurboTax, and mail a check, postmarked by 04/18/2016.
