I have been informed by the IRS that they've not received by tax return for 2023, which I filed with Turbo Tax.

I cannot find anyone to respond.

Does the IRS say that they did not receive your 2023 tax return---or do they say you did not pay your 2023 federal tax due?  Your only proof that you paid is your own bank or credit card record.

Check your account for 2023.   Does it show that your 2023 return was "accepted?"   Or does it say something else like "rejected,","printed," or "ready to mail?"  

Note:  If it says “Rejected,” “Ready to Mail” or “Printed” that means YOU have to mail it yourself.  TurboTax does not mail your tax return for you.

If you realize now that your return was not e-filed successfully, then you will need to file it by mail.  E-filing is permanently closed for past year returns.  You will need to print the return, sign and date it in ink, and mail it in.

That happened to me a year or so ago. I saw the email that said Congratulations you submitted your tax forms.

However I didn't see an email saying they accepted my tax forms and later upon searching all my old emails I saw one that said it wasn't accepted and then when I opened that year's TT, it showed return was NOT accepted. It was all because of some minor glitch in an empty text box.  Lesson learned the hard way.
