Satish,
If you have sold/short options and forgot to square off on expiry, the exchange settles the position based on how much in the money the option is. The blocked margin gets released on the same day after closing of the markets.
there is no extra levy if you are short options.
but if you are long options, the STT can go up significantly, check this blog.
