When you print your NY state return for mailing, you will get IT-201, followed by all of the required NY state forms and then a copy of your federal 1040 form.
You need to print again and be sure that the forms above are what is in the pdf file before you print the forms. The first page of the printout will have a list of the forms to attach to the return as the mailing address.
New York state does not want printed returns, but will accept and process them.
