I need live agent to see why IRS cannot locate my 2024 efiling

TurboTax gets no information from the IRS after you file your tax return.  No one at TT can intercede with the IRS for you or find out what the IRS is doing with your tax return.   You have to sort that out for yourself.

First---was the return 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 2024.

Did you e-file your tax return and was it accepted?
Only the IRS and your State control when and if a Federal or State tax refund is Approved and Issued.

You complete your tax return by finishing all 3 Steps in the File section. In Step 3, to e-file your tax return, you must click on the large button labeled "Transmit my returns now".

After completing the File section and e-filing your tax return you will receive two emails from TurboTax. The first email when your tax return was transmitted and the second email when the tax return has either been accepted or rejected.

Note - Once a tax return has been Accepted by the IRS or a State, TurboTax receives no further information concerning the tax return or the status of any tax refund.  Only the taxpayer listed on the tax return can obtain the status of a tax refund or a tax return.

To check the status of an e-filed return, open up your desktop product or log into your TurboTax Online Account. You can find your status within the TurboTax product.
If accepted by the IRS use the federal tax refund website to check the refund status - https://www.irs.gov/refunds

After the tax return has been Accepted by the IRS (meaning only that they received the return) it will be in the Processing mode until the tax refund has been Approved and then an Issue Date will be available on the IRS website.
