If I take the goods from a supplier. And Made Payment him . and I show This entry against the bill but if the money is RETURN Back , how can I enter this entry ?

Hello there, @account-siddhivi.

I'm here to provide the steps that you're going to take on how to record a supplier's refund in QuickBooks Online.

To track the refund amount that you received from your supplier, you'll need to create a deposit for the funds, then link this to the supplier's credit afterward.

Let's start with creating a deposit:

1. Click on the + New button at the left pane.
2. Select on Bank Deposit under Other. 
3. Choose an account where the amount will be deposited.
4. Under the Receive From column, choose the supplier where the refund is coming from.
5. In the Account column, select the Accounts Payable account.
6. Enter the refund amount in the Amount field. 
7. Hit on Save and close.

Once done, let's go ahead and link the deposit that we made to the supplier's credit. This process will offset the vendor's balance and links the deposit given back by your supplier.

Here's how:

1. Click on the + New button.
2. Select Expense or Cheque.
3. In the Payee drop-down, select the supplier name.
4. Leave the Ref/Cheque no., Payment date, Amount, and Memo fields blank.
5. In the Add to Expense or Add to Cheque section, select Add for the outstanding supplier credit and deposit.
6. Press on Save and close.

I'm also adding this reference about entering a credit from a supplier in the system, in case you need it on your future transactions:  How you enter the credit depends on how you record your purchases in QBO.
