The possible reason why you don't have the option to add your accountant is that you subscribe to a third-party provider such as Apple or Google Play( Check subscriptions with your app providers). If the subscription was from Intuit, you can directly invite your accountant from the Gear icon.
However, you can migrate your subscription to Intuit so you have the option to invite your Accountant. You'll need to cancel the subscription with your third-party provider and once it's your bill date we can move you over to QuickBooks billing.
Once everything is done, your billing will now be handle by Intuit, and you can now invite your accountant. In case you need help with the steps I've shared above, you can contact our Customer Support Team. Just click this article on how to reach us: Contact QuickBooks Self-Employed Support
