You will have to recreate the original return exactly as it was filed as part of this process.
For 2017, you can amend your income tax return using TurboTax Online. See TurboTax Online Product Guide.
For tax years 2016, 2015, and 2014, you must use the TurboTax CD/Download software.
- Order the software, install it on your computer, and prepare your desired year tax return as usual.
- You'll need to file a conventional paper return, as e-filing 2016 or older returns are no longer available in TurboTax.
Processing times for amended state returns vary from state to state. If it's been more than 12 weeks since you mailed your amended state return, and you haven't heard anything, we suggest you contact your state tax agency.
It is possible to amend a tax return prepared elsewhere using TurboTax but it will be a real pain. It would be much easier to use the software used originally to prepare the returns than to use TurboTax.
In order to use TT software, first you have to purchase the desktop software for that year and download it to a full PC or Mac. Then you have to re-create the tax return EXACTLY as it looked when sent to the IRS. You then tell the software you will file by mail in order to "trick" the software into thinking you filed. THEN, you use that same software to prepare a Form 1040X in order to amend the return, and print, sign and mail the Form 1040X to the IRS. It takes the IRS about 3-4 months to process an amended return. It is too late to receive a refund for an amended return for any year earlier than 2016.
To file a return for a prior tax year
If you need to prepare a return for 2016, 2017, or 2018 you can purchase and download desktop software to do it, then print, sign, and mail the return(s)
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 UPS or certified mail so you will know the IRS received the return.
