I prepared my 2023 tax on turbo tax last year but did not file. How can I find that account to complete.

 You will be able to access the 2023 return you started by using the exact same account and user ID that you used when you started it.   But you can no longer use online software for any further changes.

Start a 2024  return online and enter some personal information  so that the menu on the left opens up and lets you access your past year returns.

Online tax preparation and e-filing for 2023 returns is now permanently closed.

Now it is too late to use online software or to e-file. If you have any changes/corrections at all to make to your 2023 return, you now have to complete it using desktop software, which you must download to a full PC or Mac  (not to a mobile device).Then you need to print, sign and mail it.

If you already paid for your online software you can ask customer support for a download of the desktop software.

They are available from 5 a.m. to 9p.m. Pacific time daily

If you are getting a refund, there is no penalty for filing late.  If you owe tax due, then file and pay the amount due as shown on the Form 1040, but expect a bill later from the IRS for the penalty and interest you will owe.  Only the IRS will calculate this—TurboTax will not calculate it.

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.

Federal and state returns must be in separate envelopes and they are mailed to different addresses.  Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.

If you can't find the account you used to start your 2023 return, use this Account Recovery tool to see all of your accounts. 

1. Download TurboTax Desktop.
2. Sign in to TurboTax, using the same Intuit Account account you used to prepare your prior-year return and select Continue on the first screen.
3. On the second screen (Tax Home), scroll down and select Your tax returns & documents.
4. Select Download .tax file (not the PDF) for the prior year you want and save it to your computer.
   • If the year you're looking for isn't there, it might be in a different account. Go here to find all of your accounts. One of them should have the return you're looking for.
5. Back in the TurboTax Desktop software, select Find a Tax File, and locate the tax data file you downloaded in the previous step.
6. Select the file and select Open.
7. You can now finish filling out your tax return.
