Hello there, @patti2.
Thank for posting in the QuickBooks Community. I'd be happy to help share on how you enter the deposit in QuickBooks Online for the sales tax refund.
You can use bank deposit and use the expense account used when you pay your taxes.
For more information about this process, I recommend checking this article: How to record bank deposits.
I've added some screenshots for your reference. However, if you need additional help in recording the deposit, feel free to call our phone support. They have the tools that can help you get to the resolution quickly.
That should do it. I'm just a post away if you have any other questions about recording the sales tax refund. I'll be happy to help you out.
