K-1 BOX16 checked, but without K-3
Hello,
I traded stocks (ProShares UltraShort Bloomberg Natural Gas) in 2022 and received K-1 recently.
In the K-1, BOX-16 was checked, but without K-3. (The K-3 will be made available online by the end of June 2023).
My questions are :
1. how to fill out the tax return without K-3? 
2. TT asks to provide details of BOX 13, code, W. Which I should select? In the instructions of K-1, it says Code W. other deductions, see page 12 of the IRS instructions.

3. Which should I select for the describe the partnership? The amount on L (ending captial account) is 0.

Thanks a lot
