Were is form pa-8879 for state efile but still have to mail in this form?

[IreneS]

No.  Just sign the PA-8879 and keep it for your records.  Since your actual return can't be signed (because it's being e-filed) form 8879 serves as an authorization (or electronic signature) for your return.  PA-8879 should be signed before the transmission of the return.

To print the PA-8879 please follow these steps:

1. Click on TaxTools > Print Center in the black bar at the side of your screen. 
   
2. On the TurboTax Print Center screen, click Print, save or preview this year's return.
3. Mark the box(es) for 2018 [state] returns and your state, if amending it as well. 
   
4. In the next section, select Just my tax returns.
5. Click on the  View or print forms box. 
6. When the print screen comes up you can select the pages to be printed.
