You have a License Code? It can only be used to activate the Desktop CD/Download program. Are you trying to use it for the Online version? No. Online is separate from the Desktop program and they are priced differently. If you are in the Online version now you can just leave and abandon it and not pay for Online.
We don't understand about about the wrong 2021 code. You need to call in and try to explain it to support.
