K1 distribution taxable?

My husband was in a partnership with some friends where they each paid a monthly amount and invested in the stock market. He passed away and a few months later I withdrew the money. On the K1 there is nothing in any of the boxes in Part III, only Parts I and II.  I inherited the partnership as the beneficiary but I am still the surviving spouse. Is the distribution taxable?  Also, when I got the K1 form, it’s in his name not mine.  Will this cause any issues?
