Does anyone know why my deleted transactions are still showing up in Reconcile? I'm using QuickBooks Online.

Welcome to QuickBooks Community, info-rescuemepet.  It's nice to hear that you're using QuickBooks Online.

Let's figure out why your deleted transactions still appear on the Reconcile page. I've tried what you exactly did. I excluded/deleted transactions from the bank feed and deleted them from the register. I checked them back, and they are no longer showing in Reconcile.

First, we can use the Audit log feature. This feature record all activities made in your account. We can use it to track if someone or other users in your QBO account made changes.

1. Go to Settings ⚙ and select Audit Log.
2. Select Filter. Use the fields on the panel to choose the appropriate details.

If confirmed that we deleted them successfully, we can fix using an incognito window. This could be a browser-related issue. A full cache can be caused by odd behavior in the program.

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Option + P

If it works, you can clear cache and temporary internet files to optimize the browser's performance: Delete browser cache. Another way is to use compatible browsers with QuickBooks Online. 

I collected some articles that can help us handling our bank transactions and keep our accounts accurate from time to time:

• Categorize and match online bank transactions in QuickBooks Online.
• Reconcile an account in QuickBooks Online.

Also, we can use the Bank Rule feature to automatically categorize our downloaded transactions. Let's click this link for more details: Set up bank rules to categorize online banking transactions in QuickBooks Online.

If you have questions about reconciliation and bank transactions, please that I can be your help anytime while you're working on other tasks in QuickBooks Online. Have a good one!
