I efiled both Fed and Iowa with you yesterday. I see an IA 8453-IND. Do we sign and send this in? Is there the same type of form for Federal? I didn't see one."

No.  Do not submit the IA 8453-IND to the Iowa Department of Revenue unless requested to do so.

Since your actual return can't be signed (because it's being e-filed) form 8453 serves as an authorization (or electronic signature) for your return.

AccordingThe IA 8453-IND must be completed and signed before transmission of the return can take place. Attach to the IA 8453-IND:

• State copies of W-2 forms
• A copy of other state tax return(s), if the IA 130 was completed or the Iowa/Illinois reciprocal was claimed.

Form 8879 serves the same purpose for your federal return.
