2016, 2017, 2018 Turbotax CD activation code necessary?

Hi. My father has the CD editions of TurboTax Deluxe 2016, 2017, and 2018 that I'd like to use. He threw away the boxes though.

Do those CD editions of TurboTax require an activation code that was possibly in the box? 

Apparently, he installed one of them on a new computer and he was able to open the software, but I wasn't sure if it would eventually ask for a code and not work.

There was no activation code required for the TurboTax 2016, 2017 or 2018 software.  Only tax year 2019 has the license code requirement.
