I can share some ways so you can refund the security deposit without needing to enter the credit card credentials, Ballentine . Let me walk you through the process.

To process a partial refund in QuickBooks, you have two options. The first option is to log in to your QuickBooks Payments and perform the partial refund. Afterward, you can E-mail or Print a copy of the receipt for your records.

Here's how:

Step 1: Log in to your account

1. Log in to your QuickBooks Online (QBO) or QuickBooks Payments account. You can directly follow step 2 if you log in to your payments account.
2. Go to the Gear icon located in the upper right corner.
3. Choose Accounts and Settings.
4. Click the Payments tab.
5. Find the Merchant details section, then click the Manage account.

Step 2: Create a refund in QuickBooks Payments

1. From the Activity & Reports dropdown, choose the Transactions option.
2. Select the date range of the transaction.
3. Click Search.
4. Press the transaction you'd want to reverse, then select Reverse (Void/Credit).
5. Enter the amount that needs to be refunded, then click Submit.
6. You'll see the receipt on the screen. Select E-mail or Print to get a copy of the receipt.

Afterward, you'll see this transaction from your For Review tab or bank feeds. You can create a refund receipt, and then Match it with the downloaded transaction or Add this transaction so it can directly go to the Categorize tab.

The second option is to directly ask for the credit card number of your customer and then refund a security deposit in QuickBooks Online.
