how can I delete previous bank transactions%3F

I've got you covered, @DRS27. I'd be glad to guide you in excluding your previous bank transactions in QuickBooks Online (QBO).

Excluding a transaction prevents the program from downloading that same entry into the bank feed again. If you delete it, rather than excluding it, the system will recognize the transaction is not accounted for and will download it again from the bank. 

If you wish to exclude, please refer to the steps below.

1. Navigate to the Transactions menu, then Bank transactions.
2. Select the blue tile for the bank account.
3. Go to the For review tab and set the date in the dropdown. 
4. Tick the box of the transaction you want to exclude.
5. Click Exclude.
   

Moreover, if you prefer to delete the transactions entirely, head to the Excluded tab. Afterward, put a checkmark on the transactions you'll want to remove, then Delete.

For further details, please refer to this guide: Exclude a bank transaction you downloaded into QuickBooks Online.
