1.) I need the form that I need to sign on paper for my PA state return? Where do I get that? 2.) I need to file Philadelphia municipal taxes. How do I do that?

If you e-filed your returns then there is nothing that you have to send it. Do not mail Form PA-8453 to the Pennsylvania Department of Revenue (PA DOR) unless you are notified by the PA DOR (very rare).

PA Form 8453  is required for all electronic returns that have not selected the Federal Self-Select PIN.  Taxpayers filing electronically from home computers must keep the signed Form PA-8453 and supporting documents for three (3) years after the due date of the return, or the date the return was filed electronically, whichever date is later. Please see the below for more information: https://ttlc.intuit.com/replies/3302289

TurboTax does not support the Philadelphia tax return. If you are required to pay Philadelphia City taxes, please visit their local website http://www.phila.gov/revenue/individuals/Pages/default.aspx.
