Yes, if you efiled the NJ return and provided the bank account details for payment (which it appears you did since its on the NJ cover page), then this information gets forwarded to NJ for payment on the date you selected. There is no place on the NJ form because NJ requires efile for direct deposit/payment. So, if you were printing your return, then you would need to make the payment directly (which doesn't apply to you since your comment clarified you efiled).
