Why did entering rental income expenses not change my amount owing? I had rental income and expenses. Entering income affected the amount - entering expenses did not.

If more info is needed, please let me know

I was able to get an answer when I complained on TurboTax Canada's facebook page, and someone scheduled a callback. It was as I suspected, a simple misunderstanding. I had set the "personal" amount to 100%, thinking that meant I personally paid that much in expenses. I also put only the percentage that was expensed for the rental property. So for example, if the apartment was 30% of the square footage of the entire house, and I paid $3000 in taxes, this is what I did:
                   Amount        Personal %      Total
Taxes:              900                    100            0

what I should have done was:

                   Amount       Personal %     Total
Taxes:             3000                    70        900

Hope this helps someone else
