I did some commodity, commodity options (like SLV, GLD), ETF and ETN trading last year. I lost my K1 forms when I moved to a different state.
My broker has provided me 1099 forms which also state profits and losses.
Do I need the K1 forms to prepare my taxes? (It is due October 15, due to late filing.)
If needed, how can I get the K1 forms? My broker says he is not responsible.
