Hi, on my tax return it is asking about a K-1

Hi on my tax return it is asking about a K-1.  I am not clear on what is driving this question.  It mentions Invesco DB Commodity Index.  I don't see that as a current investment.  Could this be some type of carry over?  Maybe I should have closed this out at some point.  What tax form comes from our investment team that would have this information?  I don't see a mention of this company anywhere on the 1099s.  Is this on another form?  It is also listed as 0 nonpassive income.  I did see this on the last 2 yrs forms but each one has the same 0 non passive income and I can not find where this data came from.  Thanks
