@Hyo I have a few questions and a comment.
Do you and your wife reside in a community property state? You may be able to treat the partnership as a disregarded entity and each file a Schedule C if you elect to do so.
See https://www.irs.gov/pub/irs-drop/rp-02-69.pdf
Is there a reason you are not opting out of Section 988 treatment? Section 1256 is the standard 60/40 capital gains treatment and is typically more advantageous for profitable traders.
Your expenses, as a trader, are essentially business expenses and can be entered as such.
