If the error you are getting says that it's due to missing Payment Amount for direct debit of state Tax Payment. You will need to go back to the section where you entered your information to pay your Pennsylvania balance due.
Please make sure you have all of the information entered correctly: 1. Routing Number (9 digits) 2. Account Number 3. Valid Payment date 4. International ACH Transactions question answered.
If you have no tax due, then uncheck the "Direct Debit" option from the "Info Worksheet" under "Pennsylvania Individual" available under the "Forms" tab, located in the upper-right-hand corner of the screen.
Also, make sure the correct direct debit checkbox is chosen, depending on whether the filing is for the return. Make the appropriate changes and re-submit this return electronically. However, if the reject continues, you may want to file this return via U.S. Mail. To file your state return, print it and mail to the appropriate taxing authority.
