Hello,I have double entries in the QBO many time it happened. Would you please let me know how to solve the problem

I can share some information about processing bill payments in QuickBooks Online (QBO). 

Can you tell me more about the entries that you're referring to? That will help me provide an accurate solution to the concern that you're having. 

If this is coming from a connected bank account, you can match the downloaded payment transaction with the one you manually entered can prevent duplicates.

Here's how:

1. Open the Banking menu.
2. Go to the Banking area.
3. Locate the downloaded payment under the For review tab.
4. Click on Match. 

You can refer to this article for more information about reviewing and categorizing downloaded transactions in QBO: Categorise and match online bank transactions in QuickBooks Online.

From here, you can review your accounts in QuickBooks to make sure they match your bank and credit card statements: Reconcile an account in QuickBooks Online. 

In case you mean something else, let me know in the Reply section below. I'm always here to assist you further. Keep safe, and have a wonderful day!
