Do you mean you filed your tax return, owed federal and/or state tax due and it has not ever been paid? What did you do to pay the tax? Are you certain that you e-filed successfully and that the returns were accepted? What does it say about how you are paying your tax due when you read the page of filing instructions that prints out with your tax return?
If you did not pay your tax due by the deadline on April 15, 2024, now you are subject to late penalties and interest owed.
Did you e-file? Did you click a big orange button that said “Transmit my returns now?”
When you e-file your federal return you will receive two emails from TurboTax. The first one will say that your return was submitted. The second email will tell you if your federal return was accepted or rejected. If you e-filed a state return, there will be a third email to tell you if the state accepted or rejected your state return.
First, check your e-file status to see if your return was accepted:

You must pay your state tax due using the state’s preferred method of receiving payment. For most states that will be by making a payment to the state’s own tax website, or by mailing a check or money order.
