Get your taxes done using TurboTax

If I enter $278 for insurance for four months, TT enters for insurance $91. It is as if TT was calculating the $278 as the total amount for the year and multiplying it by 0.33 to get the amount for 4months??  .... If that is the case, in order to get the correct expense amount of $278 , I need to put the whole year insurance amount which is $835? 

It does the same for my repair, maintenance and real estate taxes that I enter; it multiplies the amount entered by 0.33.
