@IRonMaN I agree with you Iron Man and I do not attach PDF files of details either. The IRS matches up the totals that they have, with the totals on the returns,  and they only question it if the totals are different, therefore it may not be necessary to attach the detail, my friend and colleague who is a retired IRS agent said the same thing. If the IRS requests the details then one can mail them the paper copies of the details . But if someone does want to attach the PDF file to returns then that is fine also. Just my opinion
