Minecraft Java Edition license access / migration issue

Hello Microsoft Support,

I purchased Minecraft Java Edition several years ago on a Mojang account. I did not complete the migration to a Microsoft account, and now I cannot access the license. I do not see my purchase linked to my Microsoft account.

Information I have:

• Possible Java Edition username: star090720 or star0720
• Purchased in South Korea
• Payment method: Parent’s credit card
• Purchased when I was a minor

Please check whether this license exists and advise how I can recover it or link it to my current Microsoft account.

Thank you.
