Hi, I have accidentally filed the non-fillers form and now I have filled a new 1040 filer form from turbo tax. Also, I am attaching a 1040X form for amendment. But, I am confused about how to file a 1040X form. I have already filled out the basic details and part III that is the explanation, how to complete the rest of the details.
On another hand, does writing a cover letter instead of a 1040X form is acceptable by IRS and a good option.
Thanks
