I’ve gotten an IRS CP2000 notice for my 2018 return. It is saying I’ve failed to report dividend and interest income from a K-1, which I received for an investment held in my Roth IRA (ticker DBC, a commodities ETF). My understanding has always been that if the fund does not report any UBTI (code V in box 20 of the K-1) that the income is not reportable.
Do I have this wrong ? Is it because there is another supposedly questionable item on the same return (and on the CP2000), a Roth IRA contribution that was recharacterized to a TIRA contribution the following year ?
