Hello, nisaak1. Yes, your old QuickBooks accounts may have caused your reactivation issue with QuickBooks Self-Employed (QBSE). With this, let's ensure you're using the right app or website while logging in so you can access your account accordingly.

From our description, the website or app you may be using to access your QBSE account is likely associated with other QuickBooks platforms. I'd recommend downloading the appropriate QBSE app in the Apple Store or logging into your account through the correct website. From there, input your correct login credentials to access your newly reactivated account.

On the other hand, since you're subscribed through Apple, your billing is handled by them, not directly through QBSE. With this, I'd encourage you to check your Apple billing history to help us make sure your subscription is activated properly.

Once everything is all set, you may want to connect your bank and credit card accounts to QBSE for downloading recent transactions and maintaining updated financial data. For a detailed guide, please refer to this article: Connect bank and credit card accounts to QuickBooks Self-Employed.
