1065 Partnership for Multimember LLC Question

My husband has a new (2022) Michigan multimember  LLC that does work in both MI and OH. They provide a service (no goods sold and no employees) all members are equal owners so also no w-2’s and we had no 1099 payments to others. We filed the 1065 and also got the schedule k-1’s from that to the owners. 

One member lives in MI and two in OH. What/if any filing requirements are there for the states for the business—-or is that only done when the members do their personal 1040’s. Do they need to specify amount/payments made in each state anywhere or not because they are reciprocal states.  

Their gross receipts were less than 250,000.
