I reinstalled turbtax 2019, which I had bought from Amazon. It refuses to accept its product key

I use a Windows 11 laptop.   

Once I get it working can I use to ammend my 2019 CA return.

As compared to your original 2019 installation, are you using a different computer, or different hardware, such as a different hard drive?

Sorry,   You can't install or reinstall 2019 anymore. They only support the last 3 years and recently took off 2019 when they moved 2022 to the past year section. And 2019 was the first year they started using the License Code to activate the program. You can't activate it now. It will fail.

Some people at the end of this thread found how to bypass the activation for 2019
