in 2019, I bought a long-term call on SLV (Silver Trust ETF) -- for an Option Premium of $100 (=$1/sh.), with an exercise price of $16.
The Call is considered to be a Section 1256 Options and it was marked to marked on 12/31/2019 (reported a gain of $20).
In Oct 2020, I exercised the Call option. And on the 1099, a "realized" gain of $300 was reported. [So I reported a total gain of $320 (=$3.20/sh.) on the Call that I didn't receive any cash for.]
The SLV option was exercised at $16; and the brokerage firm is recording a cost basis of $17 per share ($16 + $1).
Shouldn't my cost basis for SLV be $19.20 ($16 + $1 +3.20). It would similar to reinvested dividend. And if the brokerage firm does not or would not adjust it, is there an Adjustment Code that I can use when I sell the SLV?
