The current online program can only be used for a 2020 return--no other year. You can, however, download the .tax file for the return you started, open it in the TurboTax desktop version, and complete the return.
If you need to prepare a return for 2019 you can purchase and download the desktop software to finish the return. To purchase the software, please click on this link: Past Years' Products It is not considered a "re-purchase" since you would have only been charged for TurboTax Online when you filed the return.
To access your prior year online tax return please follow these steps:
The file will appear in the Downloads folder on your computer. You can complete the return, print it, and mail it in. 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.
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 are getting a refund, there is not a penalty for filing past the deadline. If you owe taxes, the interest/penalties will be calculated by the IRS based on how much you owe and when they receive your return and payment. The IRS will bill you for this; it will not be calculated by TurboTax.
