California Sellers permit questions

[l_line]

I am currently trying to get a California sellers permit for my dropshipping bussiness, I am going to be using Aliexpress to purchase most of my products until I know which ones are selling well enough for me to purchase them in bulk. That being said I am having an issue filling out the form for the sellers permit as I do not really have any major suppliers, If anyone has any suggestions on what I should I would be extremely grateful as this has become somewhat frustrating staring at the form and not being able to answer.

Thanks in advance!
