If you did not pay during the efiling of your return through TurboTax, then YES you still need to pay.
You can pay your Federal tax online here: https://www.irs.gov/payments
You can do the same for your State return. Just go to your state's Department of Revenue or Taxation website and look for "Pay Taxes" If you filed both your Federal and State tax returns with TurboTax, there is a payment voucher for both printed with your return . If you can't find the printed vouchers, you can print a voucher from your State Revenue website, mentioned above, or from the IRS website. Hope that helps.
