Did you already efile the Federal return previously by itself? If you efiled the Federal already and are now trying to efile the state return, it won't let you until the Federal return is accepted. The IRS begins processing Federal returns on February 12, except for a small number they pull early for testing purposes.
Most NY forms are ready except for a very few. See the tables below.
