Dhaaka Topi,



For Federal filing, yes there is a way to correct the mistake (I dont know about state filings). You'll need to fill out form 1040x (Amended U.S. Individual Income Tax Return). I am not sure if any of the online
tax preparing software will let you fill 1040x. So you will most probably have to do this manually (read the instructions, it is fairly easy I did it myself once) or via HRBlock or something like that.
