While filing ITR1, I had filled incorrect TDS details, due to which I got a demand letter for about 1 lakh rupees in notice u/s 143(1). On realising mistake, I filled a revised return and also got another notice u/s 143(1), this time with no demand. Do I have to take any action on old 143(1) now? I do not see anything under "worklist" or "e-proceedings". I am afraid as the old 143(1) says that it has to be responded in 30 days, though there is no place I can respond.
