Note that Column A is marked "or as previously adjusted". Similarly, so is Line 18.
A lot of users report here that 1040-X from turbotax has problems.
When mailing 1040-X, do not include your old 1040 nor your revised 1040 because the Form 1040-X reflects any changes there and becomes your new tax return.
include in order only those Sequence Numbered tax forms and Schedules that changed or were added due to your amendment.
Attachment Sequence Number is on all the forms and Schedules that come after 1040.
If you are using TurboTax you have to do this by visual comparison. The program won't break out those pages for you.
