FDA Prior Notice for food imports via UPS

Good evening. I'm waiting for my supplier to ship me 30kg of tea that is to be sold commercialy to consumer within United States. Shipment will be completed via UPS by air. UPS sent me an email asking for Prior Notice number. After googling and youtubing for a bit - I created an online account to put in a prior notice by myself but encountered a few problems and was hoping community here could share some advice.

How can I fill up information that is marked red on the screenshot below? Whom should I contact to get such information? On the UPS website, when I access my shipment info via tracking # - it doesnt show me when exactly my package will arrive and it doesnt show at which airport will arrival be. I clicked through the rest of the application and its pretty much information about me and my supplier, which I can all fill up by myself. So only this section below arises questions I can't find answers for.

Appreciate any help <3
