okay NOW we're getting some where, You are on an expired Non-B visa/extension AND you have a letter from your embassy stating you can't travel due to Covid-19. GO to the immigration office in the city you live in and apply for an extension based on not being able to travel.
Right now any extensions applied for between Sept 27 and Oct 31 will be dated as starting on the 1st of Nov. BUT because your visa doesn't expire until Nov 10 that doesn't affect you AND possibly by then they will have the 60 day extension program rolled out and you'll get 60 days instead of 30. :)
