From 28 years of experience in the business and having taught the income tax prep course :
You only need to attach any forms or schedules that changed and support the changes in column B of the 1040X ... so for example if your only change was for some interest on the Sch B then ONLY the Sch B needs to be attached to the 1040X. Sending 50 pages of unneeded supporting docs is not needed and again can cause confusion.
From the IRS instructions ... it doesn't tell you to send extra unneeded items ... if you were the data input operator would you appreciate all the extra pages that you have to sort thru to get to the forms that you need to enter ... think about it. May I suggest you just wait for TT to have the efile option working and let the program send the correct pages.
"Assemble any schedules and forms behind Form 1040-X in the order of the “Attachment Sequence No.” shown in the upper-right corner of the schedule or form. If you have supporting statements, arrange them in the same order as the schedules or forms they support and attach them last. Don’t attach a copy of your original return, correspondence, or other items unless required to do so."
