Get your taxes done using TurboTax

If you mailed both returns to the state then the state most likely shredded or discarded the federal return.  That means your federal return was not filed at all.   You need to print it again and mail it to the IRS.
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/state received the return.

If you are getting a refund, there is no penalty for filing after the April 15 deadline.
