Thanks. I guess I will pass.
It seems that, for TurboTax at least, I will have to enter all my filing information again with a new vendor (TurboTax in this case) EXACTLY as I actually filed, and then pay ($120 or whatever it is because it's too hard to find out what my actual price will be at the TurboTax web site) just to pretend to file (by declining to e-file and say that I will mail my return). THEN TurboTax will allow me to e-file a 1040-X amended tax form.
I have not looked at other e-file vendors yet except the IRS's Free File Fillable Forms - as I said in my original post, I found no way to e-file a 1040-X with Free File Fillable Forms. Intuit TurboTax, however, is clearly not the answer.
My search so far for a way to e-file a 1040-X is failing to find any acceptable option. Remarkable in today's world.
I guess I'll be snail mailing my 1040-X. Just to change one measly (but important) check box that won't affect the bottom line. Who knows how long that will take to be reflected in the record (or how / if I will be notified when / if it is accepted or not)?
