Hi there, courtneymae99. 

I appreciate you following the steps provided above by my colleagues. I suggest seeking help from your accountant to ensure you use the correct affecting account when creating J.E. to ensure it offsets the negative balance on your sales tax payable.  

If you don't have an accountant yet, you can visit the website Find a Pro Advisor Accountant to locate one near your location who can help you with your business.  

You can check out this article about adjusting sales tax in QuickBooks: How to Adjust Sales Tax Liability in QuickBooks Online. This article contains some insights about how to adjust or zero out the sales tax balance. 

You can post a comment if you have additional questions about the negative in sales tax payable. I'll make sure to help you out. Enjoy the rest of the day!
