Where can I enter a HUD1 Property Tax? I see "Additional Property Taxes Paid," is this it? If so, my Property Taxes paid for 2016 do not add up in the summary.

I have a 1098 for my First Installment Property Taxes and I also paid Property Taxes when I refinanced that don't show up in my 1098, so I need somewhere to input the Second Installment paid.  The only area I see is an area that says "Any Additional Property Taxes Paid".  However, if I enter it there, my summary shows my Total Property Taxes being $305 short.  Why isn't it adding up?  Should I be entering this elsewhere?
