After you file

A copy of the amended federal return must be included in the e-file of the NC state amended return, per the NC Department of Revenue.  If you did not amend your federal return, this is why the e-file option is unavailable.  North Carolina requires a copy of amended federal returns even if no changes are being made.  See the requirements below from the North Carolina Department of Revenue:

"When filing an amended North Carolina individual income tax return, fill in the "Amended Return" circle located at the top right of Form D-400.  Attach Form D-400 Schedule AM to the front of Form D-400.  You must attach the following information to your amended return, when applicable, as documentation to support the changes:

• A copy of a federal audit report.
• A copy of federal Form 1040X and supporting federal schedules and forms if changes are also applicable to your federal return.
• W-2 and 1099 statements to verify a change in income tax withheld.
• NC K-1 to verify tax payments made by a pass-through entity.
• Federal Form 1040X or Form 1045, including Schedule A and B, if amending as a result of a net operating loss.
• Any other required schedule or supporting form.

Be sure to include a copy of your Federal Form 1040X if you were also required to amend your federal return. Please attach any schedules necessary to support your changes. This would include the following items: a copy of a federal audit report, W-2s and 1099s to verify a change in income tax withheld, NC K-1 to verify tax payments made by a pass-through entity, or Federal Form 1045, including Schedule A and B, if amending as a result of a net operating loss.  Note: If you filed forms D-400 Schedule S, D-400 Schedule A, D-400 Schedule PN, D-400 Schedule PN-1, or D-400TC with your original return, you MUST file these forms with your amended return, even if there are no changes to these forms."
