The reason the call-center people don't seem to know about form 1040-X is because the 1040-X has never been capable of being done On-Line. TTax has always made a download of the desktop installed software available at no charge for those that need to prepare a form 1040-X ---That has ALWAYS been a feature of the TTax On-Line product. If one were to purchase the Desktop version in the first place they would not encounter this frustration.
Also, in response to a comment you made previously, you should be aware that per the TTax license is not it is not permitted for professional usage by those preparing tax returns for clients. It is intended solely to be used for self preparation of tax returns.
