I declare rental income from an apartment that adjoins my personal home (sometimes called a granny flat or mother-in-law unit). Some of the expenses for the rental such as property tax and insurance are easily figured since the apartment is twenty-five percent of the square footage of the entire property – TurboTax requires that you enter the expense for the entire property after which it multiplies by 0.25 to get the deductible amount. However, this year I had to repair some plumbing that serves only the apartment so I want to deduct one hundred per cent of the cost, not twenty-five percent, and I cannot figure a way to do this on TT. I would be grateful for help and advice.
