I would recommend filing a form 1065 with zero and line G box 2 marked with an "x".
This will be easier for the IRS to understand as I am fairly certain this is how it is handled in 99% of the time.
Very easy and simple.
Also send it certified mail return receipt if you are not electronically filing the return.
