Getting started

Tried to reinstall TT 2018/2019.  Entered my Install code.  Then a new window popped up telling me to call an Intuit 800 number to get an 'activation code' associate with my install code.  called the 800 number and it has been discontinued.  also having problem reinstalling TT 2020 - 2022.  Different issue. After installing as well as software update, I get a pop up window indicating that the app can't connect to the internet, while the internet is functioning perfectly and even the app update was done.  What's up?
