Has anyone ever deleted their entries and information of banks to start all over due to possible errors?

Hi huesproductionsc!

Welcome to the QuickBooks Community! I hope you're having a good day!

Yes, I've tried removing bank transactions from my books. I'll guide you through it, so you can start over again.

1. Go to Banking or Transactions and then Banking.
2. Select your bank or credit card account.
3. Go to the Categorized section.
4. Select all the transactions by putting a checkmark in their checkboxes.
   
5. Click Undo and then Continue to confirm.
    

Your transactions will be removed from your books and will go back to the For Review section, where you can recategorize them before you add them back.

Here is an article for your reference: Unmatch downloaded bank transactions or move them to another account.

Let me know if you need more help managing your bank transactions. I'm just around to help.
