Please explain your issue more completely. Did you get a letter from the IRS that said you did not pay your 2023 tax due? Does your TurboTax account show that you filed a 2023 return and that it was accepted?
DID YOU E-FILE?
Did you e-file? Did you go through all three steps of the FILE section and click a big orange button that said “Transmit my returns now?”
When you e-file your return you will get two emails from TurboTax. The first one will say your return has been transmitted; the second one will tell you the IRS has accepted or rejected your federal e-file. If you filed a state return, there will be a third email (usually a day or two later) that tells you if the state e-file was accepted or rejected.
Check your e-file status:

What does it say in your account? Does it show that the return was accepted? Or does it say something else---like "rejected," "printed," or "ready to mail?”
If you discover or realize that your e-file was rejected, you will need to print it, sign and date it in ink, and file it by mail now, since e-filing is closed for returns for tax year 2023.
