IRS Direct Pay Confirmation

Yesterday, I finished my 2023 Federal Income Taxes and requested the amount due be paid through the IRS Direct Pay option.  I entered the required information, and it appears correctly on my Turbotax "Electronic Filing Instructions".  HOWEVER, the IRS Direct confirmation number did not appear on the Electronic Filing Instructions, and I have not received it in any other form.  My IRS Direct account does not show this pending payment either.  Where can I find my confirmation that my payment option was received by the IRS?  I don't want to wait until April 15th to learn that the IRS did not receive the information from Intuit.
