I read this on the IRS website but can't find the form. Where can I find it?
"
- For Form 1120-S or Form 1120-F – Attach to the amended Form 1120S/1120-F, the XML document, AmendedReturnChanges, that identifies the line number of each amended item, description, the amount on the previous return, the amount on the amended return, and an explanation of the reasons for each change."
