I received a K-1 for Energy Transfer Partners (ET), which is a MLP. Energy Transfer owns stakes in two other MLPs (USAC & SUN). The Schedule K-1 shows summary data, but there is a supplemental K-1 information that breaks out how the numbers are distributed across ET, USAC, and Sun. Also, sun reports data in Box 1 and 2, so I input that as a separate K-1.
When I first filed after owning ET, I was told I had to input the data as if I had four K-1s. One for the main ET, another for USAC, a third for SUN line 1 and a fourth for SUN line 2. I have done that.
This year there is a box 16, which says a K-3 is provided. I just received the K-3, and it shows there is no foreign income or foreign taxes paid.
So when Box 16 is checked, you have to input a lot of additional data. I looked at the K-3, and I don't see where the Box 16 data is broken out between USAC, ET, and SUN. Is all of this additional data input required? Or can I simply uncheck Box 16?
