How/where to find InstallCode *** **** *** **** *** **** CompCode *** *** *** **** ActCode ****************** ?

Bought on ebay; tried download but I was always routed to a payment scheme, (pay B4 play), then received disc and installed with the included 4-groups-of-4 characters on the disc-accompanying 'blue' sheet. Tubotax activated fine and, although not checked, I believe my last-years data has been linked. Now to the nub!

Other years, specifically 2012 through 2020, ( I did not record 2021 & 2012), I have recorded more than the 'license-to-install', which, this year, (2023 tax year), as stated above, consist of 4 groups of alpha-numeric characters. I would like to record, eg, the 13 digit computer code. And more as described in my original question.
