If you e-filed your return, you do not need to mail it in.

To check your state return for payment information, you can use the steps below to help you find your tax payment date and banking information or how you chose to pay on the return. 

• Log into your account and on the Tax Home screen, click on Show more next to "Your tax returns & documents" 
• Click on Download/print return (PDF) 
• Part VI on the State Information Worksheet will have your state auto debit date and bank account info for that payment

Generally the funds are withdrawn on the payment date you specified if your return has been accepted. If you still don't see the debit 7-10 days after your return has been accepted and your specified date, you can contact your state tax agency.
