I am also getting conflicting answers
That's because so far, you have 4 different threads you started in this public user-to-user forum on this specific topic. There are multiple ways to do things in TurboTax. So pick one thread and one way, and stick with it, start to finish.
When entering the cost basis, can I include the costs associated with the sale as well as the costs associated with refinancing the property while it was a rental?
If you're using the guidance I provided above, the program already has your cost basis, and you don't add anything to anything. The program specifically and explicitly asks for sales expenses on each individual asset as you report it's sale and the program will do the math for you, including the required depreciation recapture.
