Schedule K-1 Business Income or Broker 1099 Composite - Investment Income ?

 I received both a K1 and a Schwab 1099 Composite regarding

NuStar Energy Series B Preferred Units

I sold 100% of the units on 4/10/23

I owned the units for more than two years

Where should I enter the info ?

• Schedule K-1 – Business Income ?
• 1099-B or Broker Statements – Investment Income

TIA,

Tom
