Thank you for explaining exactly what happened to get you to this point, CDP_Chris-66. I know how important it is to keep your accounts in your Chart of Accounts organized. Let me explain the process of inactivating accounts in QuickBooks Online (QBO) works to maintain the accuracy of your financial data and get around the 1 account wasn't deactivated error you are facing.

When you connect to the PayPal app, special accounts are created automatically in QBO. With this, you'll have to make them inactive to delete them from your list. Since there were no transactions imported and you've never used the account, you can easily accomplish this task. To do so, follow these steps:

1. Go to Settings or the Gear icon and select Chart of accounts.
2. Find the account you want to delete.
3. Click the Action dropdown and select Make inactive. 

You can find more insights about the process above in this article: Make an account inactive on your chart of accounts in QuickBooks Online.

Additionally, I encourage you to make it a habit to reconcile your accounts each month. This way, you'll handle your finances and can manage them more effectively.

It was wonderful discussing this with you, CDP_Chris-66! I'm looking forward to seeing you in the Community whenever you need assistance managing your accounts and transactions in QBO. Feel free to reach out and have a great day!
