Redeeming that Windows 10 Edition code is separate from migrating to a Microsoft account. The code was just a free perk.
If you have not migrated your Mojang account yet, you have two options:
Migrate your profile to the same Microsoft account as the one on which you redeemed that Windows 10 Edition code. The benefit of this is that all your PC Minecraft is on one login.
Migrate your profile to a different Microsoft account, allowing you to double dip. You’ll end up with two Microsoft accounts, but also two Minecraft: Java Edition and Minecraft for Windows 10 licenses. It’s free real estate.
If you are currently able to login and play, then you should be good. I believe they blocked Mojang and Legacy accounts from logging into the launcher a while back.
Doesn’t hurt to check though. Make sure that the upper left corner of the launcher shows your Xbox Gamertag (may be different from your Java Edition username) and says “Microsoft account”.
If you purchased or redeemed a code for Minecraft for Windows 10 Edition in the past, your Microsoft account is eligible to get Minecraft: Java Edition for free. If you log into the Minecraft Launcher with your Microsoft, it should prompt you to set up a Java Edition username (separate from your Xbox Gamertag).

I know this comes across as one of those classic phishing emails that claim to require your immediate attention or else your account will be deleted, but unfortunately in this case it’s legitimate.
I don’t doubt there’s a market for this, I just wish for $200 it had more use cases than just “PS5 controller with a screen”. I have a Steam Deck with Chiaki4deck installed for this and while it does cost 2x, it’s a proper gaming machine and a computer.
I wonder what the internals are, and if it’s moddable.
games that are streamed through PlayStation Plus Premium’s cloud streaming, are not supported.
Would have been cool if they figured out a way to stream those games directly to the Portal.
EDIT: Looks like it runs Android, with Google’s services removed. androiddev.social/…/110939834517107216. Wasn’t aware that there were leaks that confirmed this.
