Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
Once you redeem Office Home 2024 to a Microsoft account, the license is permanently associated with that account, and there is no native way to transfer it to another Microsoft account.
Since this was redeemed accidentally, your best next step is to contact Microsoft Support directly and explain the situation. They can review your case and see if they can manually transfer the license:

Sign in to your Microsoft account.
Select Microsoft 365 > Click 'Get home support'.
Type "Chat with an agent" from the text field and press Enter.
Click "Contact support" at the bottom.
Select the product you need help with.
Follow the prompts to connect with a live agent or request a call back.
