You apply for a certificate of residence out to the Muang Thong Thani immigration office back in July 2020.
You go there to counter B to get one
You have to have filed at least ONE 90 day report (and have your receipt for the next one) in order to get it issued. They will charge you 200 baht, give you a receipt and an EMS tracking number and it gets mailed to you in about 5 to 7 days
You don't need to download the form (if that even IS the correct form 😉 ) , just fill it out there.
