You'll be unable to change your payment date in TurboTax once you filed your return and it has been accepted but you can cancel the payment and then make other payment arrangements with the IRS.
Federal Tax direct debit payments can be canceled up to 48 hours (midnight, Eastern time) before the date you designated the funds to be debited. To cancel your direct debit transaction, call (888) 353-4537.
But please wait 7-10 days after your return was accepted before calling.

For State direct debits payments you would need to contact your State directly to see if you can change the date or cancel the transaction. Each state is different. You can find contact information here.
