The software does know. When you choose to print out the state return for filing by mail, if your state requires a copy of the 1040, then a copy will print out with your state return. If your state does not require a copy of the federal 1040, it will not be included with the pages you print out to mail to the state.
But now that you have been specific about which state---include a copy of the federal 1040 if you are filing an OK return by mail.
