You'll need to enter it twice. Here's the procedure, from Rick19744:
When entering the K-1 information, you do need to set up two separate K-1's for the input.
However, you don't enter the information twice.
On one K-1 input, you would enter all the information on the K-1 EXCEPT box 2.
On the second K-1 input, you would enter ONLY the box 2 information.
