Get your taxes done using TurboTax

Thank you for your guidance.
Yes, you are right about my situation.
 
When the home sale has a step-up in home price, in TurboTax, 
1. In the page "Adjusted Cost basis of your home":  For the date bought or acquired, should I enter the original purchase date or the date of the decedent's death?
 
2.In the Adjusted Cost Basis Easy Guide: For Original Value, should I enter the original purchase price or the fair market value of the home on the date of the decedent's death?
When I click on the "Cost" explanation, it sounds like it says to enter fair market value.  Am I correct?
 
Do the home improvement, purchase, and selling expenses apply 100% to the cost basis or about 30% to 60%?
 
Thank you,
