If you still use all those saftey measures there is one way they can track tor. Now suppose you uploaded an image using tor. The Tor node taking Data from your terminal will have same byte of data as the Image size now what govt cyber listener will do is record the size of Data being sent. Next he will check the ISP for that size packet transferred. Third he will check the internet with a crawler for that size of data at the end point so this way he will intercept your entire data and can also confirm your location on the ISP. That is how Tor is tracked.
