Hi, How are you? I am Alan. I will be happy to assist you today. I appreciate your contact!
Just a gentle reminder that we are only Microsoft users like you here in the community. We are not Microsoft employees and we do not have tools to access any Microsoft System.
Susan, you must be using the same Microsoft account that was used to purchase the Bedrock & Java Edition for PC.
Go to the official Minecraft website and download the Minecraft Launcher, then install the launcher on your PC.
If your purchase is correctly linked to your account, you will see the option to play Minecraft Java Edition in the launcher at no additional cost.
In the launcher, select Minecraft Java Edition and click "Play" to start the game.

I hope this information helps. If you have any questions, please let me know and I'll be glad to assist you further.
