Hello,
No, I was not able to resolve the issue even after talking to the turbotax support over the phone.
I still have TT2019, T2021, TT2022, TT2023 and now TT2024 working just fine on my PC.
Only TT2020 is still asking for registration code and it won't accept the code I have.
I am getting error: "All available activations for that code have been used. Error code: 603"
I did not have much time to spend with the phone support so I gave up.
Also, It's unlikely that I'll need TurboTax2020 in the future.
