Your obligations depend upon the exact filing requirements for the state(s) involved.
Partnerships that have income sourced from a particular state (e.g., conduct business in that state) are typically required to file an income tax return for that state and that is concomitantly reflected in the K-1s issued to the various partners.
The site below has some relevant information concerning state filing requirements for all states. However, the information will only give you a rough idea since it is from 2017 (you should check each state's web site for the most current filing requirements).
