Did you need to reinstall them or are they still installed from the original time? Are you on Windows or Mac? For Windows the first thing I do after installing and it automatically does the first update, is to turn off the updates unless i ask it to update. Try disconnecting your internet first so it cant update 2018 and prior.
But 2019 is a special case. You will never be able to install and activate the 2019 program with the License Code. The License Code started in 2019. So 2019 needs to connect to Turbo Tax to verify the License Code. But they have stopped supporting 2019
