Nice to have you in the Community space, @AngelicaR.

I appreciate you for sharing the details with us. To post your Square credit card payment depends on how you set it up in your QuickBooks Desktop (QBDT) software.

If you have a Square bank account set up in your QuickBooks, you can create a credit card credit and use your Square account to post the payment. Let me show you how.

1. Go to the Banking menu.
2. Click Enter Credit Card Charges.
3. Select your Square account from the Credit Card drop-down.
4. Think the Refund/Credit. 
5. Enter the needed details and click Save and Close when done.

I’d also recommend working with your accountant for further guidance in recording this. This way, we can guarantee your books is well accounted for after recording this. If you’re not affiliated with one, you can visit our ProAdvisor page and look for one from there.

However, if you don’t have a Square bank account, you can use Journal Entry to post the payment. You can work with your accountant in choosing the proper account.

I’m also adding this resource that can guide you effectively in reconciling your accounts in the future: Reconcile an account in QuickBooks Desktop.
