Do I need TM30 for 1st 90 day report? LL is old and incapable of filling in online TM30, any advice?

Realtor is saying they can go to immi with me at the time of the report. I'm a little concerned.

Thanks,

I went to CW today for a visa extension based on COVID-travel restriction and got the 60 days straight without having to go back after 2 weeks. I was on Non-B prior to covid-related reason extension so I've been doing my 90 days notification at MTT on separate dates (online is not working for me after my Non-B was cancelled). I observed that IOs there were already asking for the TM47 (90 days notification) receipt and collecting 2000 baht fine for those who have none. I've witnessed 5 people under different IO experiencing this while I was waiting for my officer to finish checking the usual documents I gave him (took him 10-15 minutes to finish, which I think was oddly killing time). So just want to let others know what could be expected if you do your extension in CW.
