If you have not made any payments yet at all, you can use the Form 1040-V that will print from TurboTax with your tax return to mail in your payment. The address that is appropriate for your state of residence will be included on the voucher.
If you have made a payment or some payments, you can still use the voucher, but will want to manually reduce the payment amount by any payments already made.
If you prefer to pay online you can do so here: IRS Payments - just be sure that you indicate that it is for your 2019 tax balance due so that the funds are properly credited.
