Use of activation codes

I recently had to reset Windows. I then had to reinstall my TT products. When I went to open 2020 and 2019, I was asked to provide activation codes. I am only aware of needing a code in 2020 and it was a 14 digit code. The 2020 version reinstalled was asking for a 16 digit code, Neither of the applications would accept the "2020" code! I was wondering if anyone else has experienced this issue and particularly if a code was required for 22019?
