Are you mailing and not e-filing? If mailing then a copy is fine.

You can always substitute a copy of one of your forms if you lost the original. If you are filing by paper , though, you only submit copies of forms that show tax withheld. If no tax was withheld, you don't send the form with your return. If you e-filed, you don't send any forms at all.
