Hi there, Anne.

Thanks for sharing the screenshot. It's possible that the adjustments you've made are grouped under the "Other" line in your report.

Click the amount under the Sales Tax Payable As of Aug 31, 19 column. It will show you the transactions or source of the amounts posted under "Other". 

I would also recommend consulting a tax professional on how to record the credits to make sure your sales tax record is accurate.
