Deductions & credits

The home improvements that you did, would be added to the cost basis of the home.  They would not be itemized, they would just be added in with the price you paid for your home whenever you bought it.

The improvements that you can add to the cost basis would be things that extend the useful life of your home or change the home in some way, like an addition or a new deck, a full kitchen remodel.  Doing something like painting the walls would not add to the cost basis of your home.  Expenses for standard maintenance or repairs would not be deductible at all for your home expenses. 

To enter the adjusted cost basis, you will go to Sale of Home under Less Common Income, enter the selling price, date sold and selling expenses (realtor fees, etc) and then click next.  Then you will enter the date you bought the property and the adjusted cost basis which will include any major home improvements you did while owning the home.
