I didn’t get a grub control application this year and my lawn died off in about 1 week and now there are grubs everywhere just below the surface of the ground. Is there anything I can do at this point?

Yes, for starters a granular insecticide needs to be applied to your lawn ASAP! This will need to be watered in, thus making it effective, which will kill off the grub population. Then the excess dead grass should be raked up and removed; then your lawn will be ready for re-seeding.
