Hello, Jeff Brown. 

There's a way to let you enter the debit of $300 from the "chargeback" donation. I'll share it with you and ensure your transactions are accounted for. 

Since there aren't any invoices involved or a customer profile entered, you'll want to record the debit of $300 using a journal entry. 

To create one, go to the Company menu then select Make General Journal Entries. 

For an overview, you can use the account on where the donation went and the bank account involved. However, I do recommend contacting an accountant so you'll be guided on what accounts to use for the chargeback. 

After dealing with the "chargeback" donation, I'm sure you have other things to take care of. Our articles are always available for you to read if you need a guide or two in managing your books. 

I'm ready to help out again if you have encounter any difficulties with your tasks in QuickBooks Desktop. Just reply here or post a new thread and I'll be right there with you.
