Can I claim my Minecraft Bedrock if I owned Minecraft Java since 2018?

I purchased the bedrock console version and I own the digital copy of Minecraft for windows but can't claim the java edition

There are several different versions of minecraft. Minecraft: Java edition is PC only and can only crossplay with Java players (mac, Lenox, PC) The minecraft that doesnt have a version next to it is the play together version or more commonly called bedrock.
Bedrock is the version that can be played across mobile, console, and PC. There are also editions that are made specifically for most consoles and even a stand alone mobile version. Examples would be Minecraft: Xbox One Edition, Minecraft: Pocket Edition.
These do not work with Bedrock which is just called Minecraft. Java is the most updated version of minecraft while bedrock would be right behind that one. The others I'm really not sure how often they update them if at all. Each edition of Minecraft has to
be purchased separately. I happen to own both Minecraft: Xbox one edition and Minecraft since they released at separate times. I also have Java on my PC. As for your issue they do not have a Bedrock version on the 360.

Hello!

Yes, I already own Minecraft on my previous account. I own both Java and Bedrock edition. I have tried logging into my previous account but it still required me to purchase Minecraft Java Edition for the second time

As previously noted. Microsoft owns Minecraft, however Minecraft Java is not a Microsoft or Xbox game. The PC equivalent is “Minecraft Windows 10 edition” the Java version is a separate game not part of Minecraft bedrock, their-for not cross play with other devices.

Xbox owns W10 edition not Java edition
