Error: "Your transmission didn't go through due to duplicate Social Security number"

[frowie_w]

Try to electronically transmitted my tax return. It’s saying it’s a duplicate Social Security number and or it’s already been transmitted. I’m a little confused. I only tried transmitting it once on Friday 1-29-22z  please I need assistance and tell me the reason why it did not transmit. Thank you

Start by double-checking your Social Security number in TurboTax. If it's wrong, correct it and then resubmit your return. If you entered it correctly then...

Next check to see if you accidentally filed yourself by mistake earlier:

Check Your E-File Status on this Secure TurboTax website
How do I check my e-file status? 
- It will show the date you transmitted your return and if it was accepted or rejected.  
- Both your Federal and State will be listed separately if you filed both.
- It will tell you when you E-filed
- The electronic filing date
 

Then if it wasn't you: 

Then it's likely that another taxpayer, inadvertently or otherwise, filed their return using your Social Security number.
 

You won't be able to fix this rejection; you'll need to file a paper return and attach a copy of the IRS form 14039 - Form 14039

You "may" be the victim of tax-related identity theft.  Please see this TurboTax FAQ for information on how to proceed:
