I understand that the attachment is not being generated. New York has been late with their forms. Once they are made available, each tax program such as Turbo Tax goes through the update process to keep up with every state. Perhaps it will be made available in the next update. Turbo Tax may not even allow you to e-file New York yet if forms that your return requires are not made available. I would suggest give it a few days to allow Turbo Tax to run their updates.
