Thanks for bringing this one to our attention, Robb10505.
There are times that a sales tax amount will automatically round up when calculated based on the amount of the invoice or sales receipt. If there are a few more pennies collected, we can process a sales tax adjustment to make sure you keep an accurate record of these taxes. Just follow the steps and details in the Process sales tax adjustment article.
If the round up amount is far from the correct one, let's try opening another company file to check if you're having a problem with only one file and not the program itself. Let me show you how:
- In your QuickBooks, go to the File menu at the top left.
- Choose Close Company.
- In the No Company Open window, click the drop-down arrow in the Open a sample file icon.
- Choose a sample file and click on it.
Then, create an invoice with sales tax items. If it will provide you the exact rate, there may be a damaged data on the company file you've been working with. We can run the Rebuild Data tool is built-in to fix any company file data issues. Just follow the detailed steps in the Fix data damage on your QuickBooks Desktop company file article.

I'd like to know how you get on after trying the steps, as I want to ensure this is resolved for you. Feel free to reply to this post and I'll get back to you, Take care always.
