Sadly, (for you and every other LTR visa holder) I see a visit to the local immigration office in your near future OR a call to the LTR people at Cham Churi Square.. Just so we're totally clear this has been a huge failure compared to what they thought it'd be when they rolled it out. They sold just over 6k of these visas most in the wealthy pensioner category (people who just switched off O or OA visa/extensions) and the next category was trailing spouses OF an LTR visa holder ๐ฎ
Most offices have never seen an LTR visa holder or if they did, they've seen very few of them. Early on even the passport control officers at the airport didn't know what and how to deal with them ๐

Nope doesn't appear to be an online thing. Looks like it's an in person visit to the immigration office in the area where you live

Contact the LTR support staff at Cham Churi Square where their main office is and see what they say
**********************
To be completely honest all the people I know on the LTR have never had to do the one year reporting because it resets when you exit/re-enter the country, meaning that if you travel regularly you may NEVER have to do it
Sorry for the vague answer but believe it or not sometimes (more times than not) the real answer IS contact the immigration office OR in case of the LTR visa, the BOI division who issues them.
