2019 and 2020 are no longer available nor are they supported or provided with updates even if you find them on eBay, etc. It is too late to receive a refund for 2019 or 2020---those refunds have been forfeited. If you owe tax for those years, you owe with late filing penalties and interest and still must file the returns by mail.
TurboTax has software going back to 2021. A 2021 return must be filed by April 15, 2025 or that refund is forfeited.
Each tax year has to be filed separately using the forms for the specific tax year. They cannot be combined in any way--do not even put them in the same envelope when you mail them
It might be better for you to seek local paid tax help in a situation when you are several years behind in filing your tax returns. Do you even have all of the documents you will need to enter and show your income—like your W-2’s and any 1099’s?
You cannot change the tax year. The current online program is for 2024 only. Only a 2024 return can be prepared online and only a 2024 return can be e-filed.
Online preparation and e-filing for 2021, 2022, and 2023 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.

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.
