I appreciate the details you've shared, Jaca. I'm here to help you activate your QuickBooks Online (QBO) account.
Many subscription-based products have specific activation periods to ensure the customer starts using the service within a certain timeframe.
Since the activation period has lapsed, the first step would be to reach out to the retailer from whom you purchased the subscription. Explain the situation and ask if they can provide a new activation code or extend the expiration date. Retailers sometimes have policies in place for such scenarios and may be able to assist you directly.
After activating your QuickBooks subscription, please refer to this article to begin your QuickBooks journey: Get started and adjust settings after you sign up for QuickBooks Online.
