In TurboTax 2017, I've entered 1099-MISC amounts, but after completing those the Income Summary for "Income from 1099-MISC" shows a total of zero ($0). A software bug?

I am using TurboTax 2017 Deluxe.  I have entered amounts from three different 1099-MISC forms.  However, after completing those in TurboTax, the Income Summary page shows a total of zero ($0) for the "Income from 1099-MISC" item.  

That doesn't make sense to me.  Is this an error in the TurboTax software?  

The amount I owed in taxes increased while I was entering the 1099-MISC forms, but the value on the 1099-MISC row did not change on the Income Summary page.

Anyone know what is going on?
