Narrative:

While taxiing from ramp to runway 20, I missed taxiway parallel to runway 20 and taxied toward runway. As I was approaching runway hold lines, ground controller advised to stop, which I did. I stopped partially across the hold lines. An aircraft on final was advised to go around by local controller (who wasn't sure what I was going to do). Reason for the incursion was, I was paying more attention to the checklist while taxiing than I should have.
