Congrats! Follow the official guidance, you're at Step 2 now - https://travel.state.gov/content/travel/en/us-visas/immigrate/the-immigrant-visa-process/step-1-submit-a-petition/step-2-begin-nvc-processing.html Note that you don't book your own interview, that's only for K-1's. It'll be scheduled for you (approx 6 months after you're DQ'ed), so no need to worry about that.
And then from that website make sure you read the country specific guidelines for Manila requirements -
