Get your taxes done using TurboTax

I'm confused. I remember signing the Taxpayer Declaration and Signature Authorization on form 8879, but I'm not sure whether it was on the Federal or State return. So,  why am I told to "sign and date the Authorization within 1 day of acceptance"? That sounds like my return is not complete until I do so. Since Form 8879 is a Federal form, does that mean I need to do something else for my NY State return?

 

An answer below says Form 8879 is only for my records.  If that is correct, the instruction on "What you need to sign" would have been much clearer if it had included "for your records."
