Unless you had an extension --- which you would have had to request in 2021--- for a 2020 return, you are too late to get a refund for a 2020 tax return. The deadline to file a 2020 federal income tax return and receive a refund was May 17, 2024. The refund has now been forfeited and the IRS will not pay it. If you owe tax due for 2020 there is no limit ----you will owe it with penalties and interest until you pay.
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.
