Only certain paid tax pros using professional tax software can e-file past year amended returns. You cannot e-file an amended return that you prepared yourself using TurboTax. Your 1040X must be printed, signed and dated in ink, and then you need to mail it in. Use a mailing service like certified mail so you will know the IRS received it, since you will have a long wait for it to be processed.
NY does an effective job of scaring people into thinking they cannot file by mail.
New York prefers e-filed returns, but there are certain circumstances that make it necessary for you to file your NY return by mail and the state DOES allow mailed returns. If you could not or did not e-file your federal return then your NY return cannot be e-filed. It has to be mailed. It is not possible to e-file any state return if the federal return was not e-filed and accepted by the IRS.
