It's good to see you here in QuickBooks Community, Chad.
Let me share how a QuickBooks subscription works and ensure you'll be routed to the appropriate support so you can upgrade smoothly.
To manage your QuickBooks subscription, you'll have to contact the support team from where you purchased the subscription. As your subscription is from Apple, I recommend contacting their support team for assistance. They have all the necessary tools to access your account and can guide you through the procedure of how you upgrade your subscription.
In addition, if you want to transfer your QuickBooks Online billing from Apple to Intuit, refer to this article: Transfer your billing to QuickBooks to sign up for QuickBooks Online Payroll. This article provides a detailed guide on how to complete the transfer process.
Lastly, I've added this article for details about changing your system service level: Upgrade or downgrade your QuickBooks Online.
Please don't hesitate to contact me if you need further assistance upgrading your QuickBooks subscription. I am always ready to provide you with the help you need, Chad. Have a good one.
