How to enter sale of a rental investment property in TurboTax?

Because you pushed all the gain on the 1250 property  and nothing was applied to the 1245 properties.  That is why I told you to make a spreadsheet and sell off all the assets using the proper ratios which is the correct way to handle it.

But that is what I did, or thought I did.  After creating the spreadsheet, I went into each asset and made the sale price what was allocated to that asset.  I am not doing anything that I am aware of to determine if the asset is 1245 or 1250.  I am simply dispositioning each asset with a sale price. The land is listed separately in Part 1 of 4797.  So, what I am I doing wrong in TT?
