Your electric bill seems extraordinarily excessive.
To comment about your heating and thermostat I would need to understand it and your description doesn't provide enough detail.
A thermostat is only as good as the heating system. Smooth response and a uniform temperature is only possible if the heating system has capacity to spare in order to provide a quick recovery and rapid cycling.
Perhaps the fan keeps running to maintain a more uniform temperature.
You didn't mention what the outside ambient temperature is during the night but setting the thermostat at 74 does seem rather extravagant for sleeping. 68, winter weight pyjamas and a thicker duvet would be a much more economic temperature, especially in these times of climate change.
Mobile homes aren't noted for their insulating qualities and advancing age never improves the situation. I wager if you asked someone to bring a thermal imaging camera you would discover a great deal of your heating budget is spent warming the outside, I expect much heat is escaping through the roof, walls and windows.
The walls and roof of a mobile home simply are not thick enough to provide even the minimum thickness of insulation a permanent dwelling should have had 30 years ago...

It goes into 'override' when you push the 'override' button and goes out of 'override' when you either push 'override' again or the 'run program' button. If it is not a programmable time frame, the typical 'override' length is 2 hours.
How to reset the thermostat to shut off after 2 degrees/CT87B-4008?
on these thermostats remove the outer ring cover and in the lower right side you will see a slide adjustment. move it i believe left for closer cycles and right for longer cycles. it should be 2* on either side of set point. remember that the fan is not furnace shut off.and turning back and forth will not tell you anything. just set it and see how it works then change it again if you need to
