Let's run some tools to check if this is caused by damaged data, rosen1.
Damaged data means some information will not flow on reports and in other sections in QuickBooks, so we'll have to rebuild the connection.
From the File menu, you can hover your mouse on Utilities and select Verify Data. This runs like a diagnostic tool to check for damaged data. When it detects one, you'll be prompted to run the RebuildData tool to fix it. However, please be sure to back up your file before running it to keep a copy of the original data. You'll be prompted to do this as well before running the said tool. Please follow the detailed steps in this article: Verify and Rebuild Data in QuickBooks Desktop.
You can run the sales tax liability report again after running the tools.
Please feel free to share some news after you do the steps I mentioned.
