Its already happening in TurboTax...since they let people file before the season opens..... the returns they file already are sitting in queue at Intuit, they cant add or change anything unless IRS rejects them.

Why do amended returns take so long to complete processing?  THIS IS WHY - all these dummy DIYers that don't have their act together and file early without all their stuff and end up clogging up the amended return processing department. in Feb and March.
