Your proof of payment is dependent on how you chose to pay the taxes owed.
A canceled check if paid by mailing a check with the payment voucher, your bank account statement showing the amount paid if paid by direct debit or your credit card statement showing the payment if paid using a credit card.
TurboTax does not know when or if you paid the taxes owed so TurboTax would not have a receipt since TurboTax did not provide the payment.
