My wife died as a result for a rental property asset should I enter the stepped up bases cost from her date of death as the amount paid for it to calculate depreciation?

After the death of my wife I converted my home to rental property.  In the Turbo Tax section Tell Us About This Rental Asset I must enter the COST: The amount you paid for it.  Also Date Purchased or Acquired.  I originally paid $320K in 1994 when I purchased the property.  I am allowed a step up in basis to the current market analysis on the date of my wife’s death 3/28/2012. Which is $600K.

My question is can I enter the stepped up bases cost $600K and a Date purchased 3/28/2012?
