I'm using TurboTax to amend my 2015 return because I did not take asset depreciation of my rental property. After some inputs, TurboTax has produced a packet of 15-page documents, including a cover page, 1040X, Form1040 for 2015, Schedule A, Schedule E, Form 8863, Form 4562, Electronic Postmark. Do I need to mail IRS the entire packet or do I need to mail IRS only those forms related to the amendment, such as Form 1040X, Schedule E, and Form 4562? Thank you!
