Hello @tandy1000, I'll help record a vendor refund.

In QuickBooks Desktop for Mac, the refund or credit created is linked to the vendor's profile and can be found in the discount section. Therefore, we'll have to click the Discount Info button and select Credits to see the vendor refund recorded.

I'll add the article you shared to continue following the rest of the steps needed to record and apply the refund: Record a Vendor Refund in QuickBooks Desktop for Mac.

I've also got you this reference for a compilation of articles to use while working with vendor bills and credits: QuickBooks Desktop for Mac - Vendors and Expenses.

If there's anything else that I can help you with aside from recording a vendor refund, please let me know by leaving a comment using the Reply option below. I'll be here to lend a hand. Take care always!
