Deductions & credits

Hello, I was wondering if you can help me too. I am having a difficult time trying to figure out how to input the sale of our second home in TurboTax 2021 Premier. Thank you for the detail above. My question, how do we enter the information when we have two 1099-S forms. We sold our family home (owned by 3 sisters) to one sister.  How do we enter expense's related to the sale of the house? The 2 sisters 'selling' paid for all the expenses associated with the sale. How do we enter the renovations and improvement to the house through the years we owned it? Do we split it into 2 or 3? Thank you so much for your help.
