I had an interesting interaction with TurboTax/Intuit today. I tried to run my 2019 tax program to check a detail on my taxes. I was asked for the license key, which was rejected.

I logged on the TurboTax and went to the download page, located my version and saw that the license number has not changed. I re-downloaded and got the same failure.

I turns out, after an hour on the phone, that when Intuit stops supporting a given version, they invalidate the license so whether or not the software works, you can’t use it.
