Yes, if you have already filed, you can verify the scheduled debit date by accessing a copy of your complete tax file. The scheduled debit date would be located on the State Information Worksheet. If you prepared your State return in TurboTax, and selected to pay by check, the program should have prompted, you to print out a copy of your return. Included in that print out should be filing instructions along with a voucher form and State's payment center address. 

NOTE: When you schedule a payment for taxes due, the payment information is forwarded to the processing government agency. TurboTax is not notified of your payment status. You can contact your state tax agency, How do I contact my state Department of Revenue? and choose your state for their contact information.
