Correction Proposal Letter from IRS (SLV iShares ETF)
First of all, I am certain that this letter is legit so no worries about scams.
Background: I got a letter from the IRS regarding my FY2020 return. The letter states that my return does not match with information supplied to them by my broker. After reading the whole thing, they are correct. When I filed my 2020 return, my broker (Merrill Edge) sent out my 1099 in February 2021 so I used those to do my taxes. However, said 1099 did not include 2 trades I made (both for SLV iShares ETF), which I now know is treated differently than regular stocks or ETFs. I made enough trades that I assumed all my trades were there. They did provide an additional 1099 in March 2021, but I had not seen it until I went looking after receiving this IRS letter. This late 1099 is ONLY for those trades which the IRS is highlighting. The problem lies in that for this particular type of security, Merrill only reports the proceeds and NOT the cost basis, so the IRS is calculating a large owed amount. I actually lost money in those trades (whomp whomp) so I think I should be getting a refund. I did my 2020 taxes using TT. I know that I have to respond / do something about this.
Question: Should I, a) respond to the letter disagreeing to the correction and providing the 1099 with those trades so they can capture the cost basis (and theoretically issue me a refund), OR b) Submit an amended return thru TT to add those trades and respond to the letter with a copy of the 1040X and missing 1099, as this would directly mean I am expecting/requesting a further refund.
I just find it hard to believe they will correct the math in my favor (cost basis larger than proceeds) and issue me an extra refund unless I amend.
