Thanks for joining this thread, rdonaldosn. Making sure you're able to reactivate an account in the Chart of Accounts is something I can help you with. 

If you're using QuickBooks Online, we need to make sure that the Include inactive option is enabled to show inactive accounts in the Chart of Accounts. Here's how:

1. Click Accounting in the left panel and choose Char of Accounts.
2. From the Chart of Accounts screen, click the Gear icon.
3. Enable the option to Include inactive.
   
4. You'll see the Make active button.
    

However, if you're using QuickBooks Desktop, we can follow the steps below:

1. Click Lists at the top menu bar and choose Chart of Accounts.
   
2. At the bottom, enable the option for Include inactive.
   
3. All the accounts with x are inactive. Right-click the account and select Make Account Active.
   

To help you organize your chart of accounts, you can visit the following articles. These will provide you with links and steps on how to use account numbers as well as create sub-accounts in QuickBooks:

If you have other activating account-related concerns, please let me know. I'd be more than willing to lend a helping hand. Have a great rest of your day, rdonaldosn.
