Day Trading Tax Treatment — missing 1099 from defunct exchange

Quick background on my situation — any input appreciated.

missing 1099 from defunct exchange. I've been dealing with this for about 8 months now and the situation isn't improving.

I have already consulted briefly with a lawyer but got conflicting advice.

What's the typical outcome in situations like this?

I've dealt with this before.

In my case, it took about 2-4 months to resolve. The key was hiring an attorney to send the initial letter.

I went through almost the exact same thing.

What worked for me was escalating to a supervisor/manager. It took 1-3 months but was worth it.

Just want to point out — the statute of limitations might be a factor here. In some states it's as short as 1-2 years. Don't sit on this too long.
