We are attempting to efile a New York Fiduciary return with an electronic payment of the balance due.  It is a multistate Florida Trust.  All efile diagnostics are cleared.  We use the Efile wizard to efile the return.  The federal and all states are transmitted except NY which does not even transmit with an error that is not a diagnostic and says that NY does not recognize the entity and also some reference to a duplicate attachment, which does not exist.

Any experience with this and how to cure?
