"Should I be looking at "Mark-to-Market P/L statement and taxes". have you made a valid Mark-to Market election with the IRS under IRC 475(f) if not then you need the P/L for only realized gain/losses. FYI MTM accounting includes unrealized gains/losses because at the end of the period you include unrealized gains/losses with a valid 475(f) election.
it seems you haven't made it otherwise I'm certain sure you would know. to make the election it must be file by 4/15/xxxx with either your income tax return or extension for the year preceding the year the election is to take effect. if you haven't, the earliest you could is 4/15/2024 with your 2023 income tax return or valid extension and the election would be effective for your 2024 income tax return.
there are pros and cons to this election and there are certain criteria you must meet so I would suggest you meet with a tax pro to go over your situation. electing when you're not qualified could have disastrous tax consequences.
