How do I file last year's return?

[xmasbaby0]

You cannot change the tax year.   The current online program is for 2025 only.   Only a 2025 return can be prepared online and only a 2025 return can be e-filed.

Online preparation and e-filing for 2022, 2023, and  2024 is permanently closed.

Note:  The desktop software you need to prepare the prior year return must be installed/downloaded to a full PC or Mac.  It cannot be used on a mobile device.

 If you need to prepare a return for 2022, 2023, or 2024  you can purchase and download desktop software to do it, then print, sign,  and mail the return(s)

You may also want to explore purchasing the software from various retailers such as Amazon, Costco, Best Buy, Walmart, Sam’s, etc.

Remember to prepare your state return as well—if you live in a state that has a state income tax.

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 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.

It’s too late to file prior-year tax returns on TurboTax Online.  You will have to purchase TurboTax Desktop and install it on your computer to prepare your 2024 tax return.  You should prepare 2024 before you prepare your 2025 tax return.
