You received bad advice about not needing to turn shipped eggs. Studies have proven that it is more critical to turn eggs early during the incubation period. During the latter stages, turning is not critical because the fetus moves enough on its own.
I have tried all the recommended methods for shipped eggs and have not found any of them to have any benefits. I let shipped eggs warm to room temperature before adding them to the incubator. Once they are added, I start the auto turner. I do not get any worse hatches by doing this and I do occasionally get the benefit of ones hatching early because they were kept too warm during transportation.
