@rajG something may not be correct.
The first column is just the income from the Federal Income tax form, so Line 16 of the NC form you reference should be equal to Line 11 of the Federal Form 1040. Yoiu should be able to trace every number in lines 1-15 back the the federal form, lines 1-10.
Since this is just a mapping of income from the federal form to the state form, I am hard pressed to understand why you would have a large negative number.
Do you know why there is such a large negative number in the 'federal column' on Line 15? What is on Line 8 of form 1040?
are you doing this in turbo tax? that mapping should occur automatically.
the right column is the income you earned while a NC resident.
