CRA changed my total payable to a lower amount because of a calculation error for line 43500. All my entry info is correct. What did Turbo Tax calculate wrong?

While it can be frustrating, it’s common for the Canada Revenue Agency (CRA) to make a tax return assessment that is different from yours.  

The reasons for these discrepancies may vary and can range from very simple (typo or data entry error, forgotten slip, receipt, amount, etc…) to complex (carry-forward amounts not included, accounting errors, etc…). 

In most cases, the CRA will explain how they calculated your tax refund or balance owing, and you can find this information on your Notice of Assessment (NOA), under the heading Explanation of changes and other important information. Compare the line numbers on your NOA and their corresponding values with those entered into TurboTax.

Curious if line 42000 matched?

Yes, 42000 matched. It was only the calculation in 43500 that changed.
