You need to have two separate K-1 inputs as recommended by TT. However, one input you will enter all K-1 items except box 3. The second K-1 input will be ONLY box 3.
There should not be any doubling of tax if handled as noted above. The reason for separating the K-1 information like this is so the rental real estate can be handled appropriately.
