How do I tell if I paid my tax bill online via Turbo Tax program?

Check your own bank/credit card records to see if the payment was made.  That will be your only proof.

To verify the date that Federal funds will be withdrawn from your account, confirm that funds have been transferred, or cancel the transaction up to 48 hours before the date you designated the funds to be debited, call the IRS at 1 (888) 353-4537.
