Is Idaho your non-resident state? If not, complete Massachusetts first.
If Schedule 2K-1 doesn't report Idaho income, the entry on the Idaho return should result in zero flow-through income to that state from your investment. If this is not what you see, restart the Idaho interview and look for a section on income adjustments, business income, etc. Every state is different.
You MA return should reflect the 2K-1, but not Idaho.
