There is no confirmation number for a tax payment or a direct debit. TurboTax sends the bank information you entered with the federal tax return. The IRS then debits your account.

Go to this IRS payment website to pay any federal taxes owed - https://www.irs.gov/payments
To view the bank information you entered for the direct debit it will be on the Federal Information Worksheet in Part V of the worksheet.
