Hello
The code is only for redemption use, once redeemed, the subscription is already tied to the Microsoft accoutn used, and the code will not be needed anymore.
So, since you said your daughter activated it in June, that tells me that the code was already used, so the subscription is now in her account.
Make sure she invited you/your Microsoft account to her family plan. Have her use this instructions to invite you: https://support.microsoft.com/accounts-billing/subscriptions/share-your-microsoft-365-subscription Once you accept the invitation, you can sign into your microsoft account using this link to find the install option. https://account.microsoft.com/services/microsoft365/install#
