You don’t need to file Form 4868 (by mail or by TurboTax)
if you make a payment using the IRS
electronic payment options. Your extension will be automatically
processed when you pay part or all of your estimated income tax
electronically. You can pay online or by phone.

You can pay all or part of your estimated income tax due and indicate that the payment is for an extension using Direct Pay, the Electronic Federal Tax Payment System, or using a credit or debit card. Your extension is then automatically granted and you will receive a confirmation number for your records.
