I was sharing what my specific experience was with amending a state return. Now, this did occur a year ago, and I've only ever done it the one time. I saw another poster stated that a state amended return could be e-filed, if the federal was also amended and e-filed. Maybe things have progressed since last year. Even so, I never considered attempting to send an amended federal return, because I had no need to amend it. (The way I'm wired, I would never do that anyway, unless that was the only way one could proceed.) I saw that I could stick to amending the one state return, since the error did not impact either, the federal return, or the other state I'm required to file in. I can only tell you, once I completed the amendment process, the TurboTax generated filing instructions stated, paraphrasing here, e-filing the return was not an allowable option. Assuming the e-filing of a state return, regardless of whether it was the original or amended is not free, I saved $25, well approximately $24.40, because I did have to use a postage stamp to mail it.
The only other thing I can reiterate, unlike what the other posters said, was that I found I could bypass the federal amendment process and jump right to the state amendment section. Yes, I had to mail the return in, but it was an easy thing, the state accepted the return, sent my refund promptly, end of story. That is pretty much all the more I can say to you at this point.
