PA-8453 Form: Signature Requirements

Turbotax advised me to sign PA-8453 form and retain it in my records.

 

This form has entries for 3 signatures: The taxpayer, the ERO, and the paid preparer.

 

Do I just sign and date the taxpayer area?

 

If this form is requested by the state, do I send it to them with the ERO and paid preparer section blank?

 

Thank you.
