I guess you can log PIC for the times you were training in the left seat for a PIC position and SIC for the times you were training for SIC position. The numbers won't add up if you have other sim time (flight engineer).
Dual received would be when you were in the sim for your instrument rating. Instructor if you were ever a sim IP.
I don't think it is a very well designed grid. My opinion is that perhaps it's there mainly to see if you have been through simulator training before.
