In the K-1 worksheet there is a section for ownership %, sharing of profits % and sharing of loss %. The ownership in your situation doesn't change, but the other two do.

If due to the math of your details below that won't work, then there is another Section on the K-1 worksheet for Special Allocations, by $ or by %.  You may end up having to do an Excel worksheet to get to the bottom line for each owner and input it into the Special Allocation Section.  Note, if you do this then on the Schedule K worksheet you have to add the Special Allocation code (A-D or 1-4) so the program knows where to get the override.
