apologize if the following questions have been asked before!

I entered Thailand with a 1 yr retirement visa on May 11th and I believe I m gonna do my 1st 90days report very soon.

1) is there a range of days I can do my 90 days report?

2) what documents do I need when doing the 90 days report ?

3) does the Immigration office accept online booking for an appointment ? if so, any links?

4) I live in bangna area, which Immigration office should I attend?

5) or alternatively , could I do my 1st 90 days report online ?

Sorry for taking your time and thank you so much for your advice !
