How to stop automatic updates to 2020 CD version software Home & Business?

Hi,  I'm running 2020 CD software Home & Business. Windows 10 (!)

When I installed the software to PC, an installation box on install screen stated that Updates would install automatically upon opening the software.  It also said I could change this procedure at online site under Preferences.  I don't see where though. 

I really prefer to choose when Updates occur.

Reminder:  I am not using the online version of 2020 Turbo. I'm using my own installed software.

 

Thank you.
