You were on a Tourist Visa entry.
Then you applied for a Non-O 90-day visa, based on retirement, at your local immigration office.
As they did the home-visit, it would seem they did, in fact, accept your application.
When they accepted the paperwork, they should have put an "under consideration" stamp in your passport, with a date you should return to the office for the final-stamp. That "under consideration" became your "permitted stay" now - not your original Tourist Visa permitted-stay.
If they failed to put the "under consideration" stamp in your passport, after accepting your Non-O 90-day visa paperwork (TM-86), I would return to that office and get that done. First, check previous pages of your passport, as they sometimes find an unused-area on an earlier page to place a stamp (out of order).
