You noted in your original posting IRS Direct Pay Confirmation
Since the IRS has an option for Direct Pay on their payment website I assumed, incorrectly, that is what you were referring to.
TurboTax uses Direct Debit from a bank account for the taxes owed. TurboTax does not receive any confirmation from the IRS that the payment has been received or debited from a bank account. The IRS does not send confirmation of a direct debit from a bank account to the taxpayer.
Your proof of payment is when the IRS debit your account.
You can also see the payment in your IRS Tax Account - https://www.irs.gov/payments/your-online-account
You can call IRS e-file Payment Services 24/7 at 888-353-4537 to inquire about or cancel your payment, but please wait 7 to 10 days after your return was accepted before calling.
