Instalment Payment - Summary Does Not Match Data Entry

I am using TurboTax Online

On the page where I enter tax instalments paid for last year, I entered the amount.

However, when I review my Summary details near the end of the process, the "Tax paid by installments" is double the amount that I entered. As a test, I returned to the original question and changed my answer to ZERO.

Now, on the Summary details, it shows the CORRECT amount for "Tax paid by installments". It's almost as if the software already knows about my installment payments but this does not appear anywhere on my CRA Auto-Import details.

I'm not sure now best to proceed.
