do preferred shares produce a k-1? At least some.
for example, look at Energy Transfer on the Tax Package Support website - yes there are k-1's for their preferred shares. You can see if your MLP preferred shares are listed but Tax Package Support is not used by all MLPs.

Never owned MLP preferred shares so don't know much about them. you can always try to contact stockholder services for the company or even ask the broker.
