I have two K-1s, with ~$3,500 and $1,270 in Line 5 interest earned amounts. I understand that in general amounts over $1500 get reported on Schedule B, but I'm also sitting on $90,000 in passive carryforward losses that I would have thought would offset these gains, especially given I haven't sold nor received any interest dividends from either partnership fund. Any insight would be greatly appreciated.
Yes, you should track these amounts as they increase your tax basis. The amount of your basis will determine any gain or loss you will report when you dispose of the interest in the partnership. When you eventually sell your partnership shares, your gain or loss is calculated as the difference between the selling price and your adjusted basis.

So, doing more research, Lines 5 & 6 interest and dividend amounts are not considered passive income, which explains why not being offset. But still, I did not receive any interest directly, so much be showing up in the value of the investment/partnership -- I'm guessing I'll need to track those amounts for whenever I do sell/liquidate for the investment basis?
