Thanks for your reply. I was able to e-file, and it has been accepted.
At the time of filing, TurboTax prompted me to print, sign and mail "these documents" (it was a hyperlink), which I attempted to do unsuccessfully. Upon return to the site to try again, the link to "these documents" is no longer available (or if it is, I am unable to locate it).
What is not clear to me is what forms need to be printed, signed and mailed, and where to mail them. I can download and print the 1040-X, but it is the entire return (as opposed to select forms) and does not include the usual mailing instructions?
