Lost my TT Home & Business 2020 Key and when I updated my computer from Win-10 to Win-11 it made me reenter the key to every year - recoverable without the disk?

Maybe someone else will jump in here, but I don't believe you can activate a 2020 version of TurboTax at this point. 

Currently, Intuit is only supporting tax years 2022-2025 with respect to their activation servers.

Perhaps someone else on the board can assist.

Hmm, I didn't need my codes.  I have Home & Business.   In June 2025 I upgraded my Windows 10 laptop to Windows 11. All my Turbo Tax programs back to 2019 were still installed and work.   Even the years before 2022 that are unsupported.  I didn't need to reinstall them or reenter the License Code for any of them.

But if you don't have 2021 and prior working then you won't be able to reinstall it even if you have the License Code key.  They have stopped supporting 2021 so you can't install them or update them or download any state programs you need.

They're probably hiding somewhere in your Windows registry and they made it through the upgrade intact.
