Contact your state's unemployment office to get copies of Forms 1099-G for those years. TurboTax Online only supports the current year's tax returns. You can, however, use the TurboTax desktop program to file previous year's taxes. You will only get a refund if you had more taxes withheld on forms w-2 and 1099 than you owed for the year.
That will be two completely separate tax returns. Do not try to combine them in any way. Do not even mail them in the same envelope.
You cannot change the tax year. The current online program is for 2023 only. Only a 2023 return can be prepared online and only a 2023 return can be e-filed.
Online preparation and e-filing for 2020, 2021, and 2022 is permanently closed.
To file a return for a prior tax year
If you need to prepare a return for 2020, 2021, or 2022 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 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.
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.
You will need your 1099G for the unemployment compensation that you received.
UNEMPLOYMENT COMPENSATION
Unemployment compensation is taxable on your federal return.
You will have to enter a 1099G that is issued by your state.
Some states will mail out the 1099G. Or you might need to go to your state’s unemployment website and use the password, etc. that you have been using to certify for weekly benefits to get your 1099G from the state’s site.
Enter your 1099G in Federal>Wages & Income>Unemployment
Go through the screens very carefully, making sure to enter any federal/state tax you had withheld from the unemployment.
Most states with a state income tax do tax unemployment benefits
AL, CA, DC, NH, NJ, and PA do not tax unemployment
