Welcome to TLF! Glad you're here!
I would probably wait until the sod is greening up to fertilize - if it is dormant there will be little/no nutrient uptake.
I wouldn't scalp or stress the turf in any way until it has established/rooted.
The Prodiamine label says "To avoid turfgrass injury, do not apply to newly set sod until the sod has rooted and exposed edges have filled in."
