Human Factors
On flight into MSP. I was PM (Pilot Monitoring) and at 1;200 feet AGL was told by ATC to look for a helicopter at 10:00 o'clock and 600 feet below.  I did not see traffic and responded with 'looking'.  The helicopter reported us in sight and they were told to pass behind the aircraft and he repeated that request.  Shortly after; we got a TA and traffic was 200 feet below and close by at 11:00 o'clock.  Captain deviated slightly from glide path and localizer but not to full scale deflection.  At this time we looked to the left and the helicopter was only 200 feet away and banking hard to the right.  It seemed as if he only just saw us.  We continued and landed with no further incident.  There's not much we could have done different; I believe the helicopter saw different traffic as he should have never been that close to us. Helicopter reporting us in sight and not providing adequate separation.
