Thanks for reaching out. As long as your channel meets the YPP eligibility and thresholds, you can expect to hear back soon. It might take a bit of time as all the applications are being reviewed manually. It may take longer if your channel is held for an additional review.
You may not have enough *public* watch hours to be eligible for review. Creator Studio shows public & private combined, but you need 4k public hours alone. Try switching private videos to public, or if you've deleted videos you may be ineligible: https://yt.be/help/YPP-review
