Unless you e-file your federal return and it is accepted, you cannot e-file your state return. If you file your federal return by mail, then you also need to print, sign, and mail in your state return.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS received the return.
