My son's college financial aid office asks me to submit Form 1065 for Schedule K-1 for 2021 year but I do not see 1065 in my 1040 while Schedule K-1 is shown. What to do?

They said [federal K-1s/1065s for Proshares Ultra Bloomberg Crude Oil, Proshares Ultrashort Bloomberg Crude Oil, and United States Oil Fund.]
