If you prepared your tax return in TurboTax, the program it should have prompted, you to print out a copy of your State return. Included in that print out should be filing instructions and a Form PA40-V. Include your payment with the voucher and send it to the address on the instructions. You can also pay electronically on your state's website link below.
Pennsylvania Department of Revenue states that you can pay Pennsylvania taxes directly through your personal savings or checking account through the department’s e-Services Center
Credit or Debit Card Payments: Use your American Express, Discover/NOVUS, MasterCard or Visa to pay Pennsylvania taxes over the Internet or by phone by visiting www.officialpayments.com or calling, toll-free, 1-800-2PAYTAX (1-800-272-9829).
Thank you for your QUICK and SAGELY advice! Know however it is incorrect for this year as no such instructions were provided by the application nor a voucher provided. All other prior years I was able to view such instructions and vouchers. It may be that I opted for electronic payment, however, I believe my RTN provided was solely for my federal return, which is stated on my federal return, but no such instructions nor ePayment information is provided on the state forms.
You should be seeing a cover letter for Pennsylvania and Form PA-40V. Estimated vouchers will print if you indicate you want to make estimated payments. I see them in my copy of TurboTax.
The instruction for Form PA-40V say:
