When received vendor credit note, how to entry into quick book?

Welcome to the Community, @xiuen-wong.

Entering vendor/supplier credit in QuickBooks Online (QBO) can be done in four easy steps. Refer to the steps below:

1. In QBO, go to the + New option at the top left to get to the Supplier credit or Receive supplier credit.
2. Choose the vendor/supplier in the Supplier dropdown.
3. Depending on how you record purchases, enter the necessary information in the Category details.
4. Hit Save and close.

If you want to apply this credit to a bill, consider checking out this article and proceed to the If you enter bills you plan to pay later section for further guidance: Enter a credit from a supplier.
