I just received a 8009-A form that says I need to complete the Form or Schedule E to support line 1 on my 1040-X. What does this mean?

The IRS sent you’re a notice because you filed an amended federal income tax form (Form 1040-X) that did not explain or fully explain why your income changed. Part III of Form 1040X asks for an Explanation of Changes. You either did not fill that out or did not provide a full explanation.

The IRS is asking for Schedule E. Did you add/change a rental property or royalty to your return, add/change a Schedule K-1 or some other passive income?

Use Form 8009-A to provide a detailed explanation of why your income changed or send in a copy of Schedule E, Supplemental Income and Loss.
