I have been credited for an over payment from a supplier and I have put that in as a supplier credit. The money has come into the bank. How do I link them together?

Hello Stbsbookkeeper, 

Welcome to the Community page, 

In order to link them together in your Quickbooks account, what you would need to do is a bank deposit to creditors then use cheque to link the deposit and credit together then you will be able to match it at the banking page.
