Schedule K-1-p Who Is Responsible for Paying This Amount

1. this k-1 was sent from a mgt co. Line 55 says: “Pass-through withholding or investment partnership withholding.”  then there is a numerical amt of $676

2. i rcv’d a letter from IN saying i owe this

3. my question: is this something the mgt co. was supposed to pay (e.g., as part  their tax return) OR was i supposed to pay this? 

4. i rcv’d a refund the prev yr in case that matters. 

thank you in advance.
