Why do I need to pay extra tax to the state that I have rental?

I live in Texas and I have a rental in North Carolina, and I pay 1% real estate tax to NC each year. When I do the state tax return in Turbotax, there is no place for me to enter the tax that I have paid to NC, and by then end it says 

 

$0

NC TAXES ALREADY PAID
 
And I ended up owing NC for some extra tax money. Is this correct?
