Q.Seed Planting In Winter
Most seed packets recommend planting in the fall or the spring after risk of frost. I am in the northeast, is there a difference between planting seeds in the fall and planting in, say, February if the seeds don’t need to be buried and the surface of the ground isn’t frozen or snow covered?

This is dependent on the plant type and exactly which zone. You will want to follow all instructions for zone 5 since that will dictate what and when you can plant. This information will be on the back of the seed packet. In your area, you will still be experiencing times of frost, so you will have to take into account your last frost date for most seeds.
Right now, carrots should be direct seeded, where as something like peppers should be started indoors at this time. Everything you need should be on the back of the packet of each seed, though, so following those instructions will be best.
