Hi.
I have some questions about Amended Return. Let's say I forgot to add form 8949 and Schedule D. I want to amended a return and add those 2 forms and "MAIL" to the IRS. I like to know do I have to attach a whole corrected 1040 forms with all schedules including with the new attached forms 8949 and Schedule D? Or, I just attach forms 8949 and Schedule D behind 1040X and mail to the IRS?
