You may want to have the person you got it from double check their source. It looks like the BE N. macrophylla seedlings not N. villosa
This is the BE N. villosa
for reference.. the BE N. macrophylla (slightly larger than your plant)
notice though the much more pronounced wide green wings like your plant vs the N. villosa as well as the shape.. fatter tubbier..
The leaf shape is different too.. N. macrophylla has much more oval shaped leaves
