I accidentally delete a chart of accounts checking account? How do I get it back?

Let me assist you in activating the deleted account in QuickBooks Online (QBO), @stinson83.

Deleting an account in the Chart of accounts isn't possible. You can only make the account inactive. To reactivate, locate the inactive account and change its status back to active.

Here's how:

1. Go to the Gear icon.
2. Under Your company section, select Chart of Accounts.
3. Click the small Gear icon, then tick the Include inactive box.

 4. Locate the inactive account and click Make active.

Furthermore, here's an article you can check for guidance in reviewing and categorizing downloaded transactions: Categorize online bank transactions in QuickBooks Online.
