1. Check your passport. If you entered on a 30 day visa exempt, you would go to Muang Thong Thani. If you entered on a 60 day tourist visa, you will go to Changwattana.
2. You do not need an appointment, however if you want to make an appointment, read this post:
Most immigration offices are strict about the 2 months before, and 3 months after requirement for the 800K THB in banked money. I say most because there's 70+ immigration offices and I'm not familiar with all of them.
If the hotel didn't do the TM30 for whatever reason, then there's nothing you can do 🙁
Here's what you can expect (Note: I'm assuming you're getting a 30 day extension of stay based on tourism or a 60 day extension of stay based on unable to travel due to COVID-19):
1. Bangkok immigration is hit-or-miss with the TM30 requirements. Sometimes it's asked for, sometimes it isn't. If they don't ask for it, don't tell them you don't have it.
2. You *COULD* be fined 800 THB. If you are, you will be sent to Muang Thong Thani, Counter B, to pay the fine.
3. The immigration office will simply verbally tell you to return with the printout from the TM30.
I recommend showing the hotel what a TM30 looks like; they may not be familiar with the term "TM30". I'm attaching printouts of accepted TM30s. The middle and bottom image are accepted from the computer system.
You did not renew anything. Given what you are describing, it sounds like you got a:
One Year Extension of Stay based on Being Over 50/ "Retirement" from a Non-OA Visa.
The key word is "Extension of stay". You are *NOT* on a visa, and that visa expired a few years ago.
For a brief refresher about visas:
A Non-OA VISA is a multiple entry visa, acquired outside of Thailand, is valid for one year, and on each entry allows you to stay for a year.
A Non-O VISA is a single entry visa acquired outside of Thailand, is valid for 90 days, and on entry allows you to stay for 90 days.
An in-country Non-O Visa is a "ZERO ENTRY" visa acquired INSDIE Thailand, is valid for 90 days. It's "Zero Entry" because you acquired inside Thailand.
Depends on the immigration office. I would ask Muang Thong Thani Counter A (where the 90 day reports to processed) to confirm. after you get your ED visa.
You can apply for a 60 day extension of stay based on unable to travel due to COVID-19. I have not heard of any Americans being rejected for their first 60 day extension of stay based on unable to travel due to COVID-19 yet. See my "Featured/Pinned" post
