Well, I asked the question and the answers were ambiguous. So I sent everything. The original, the revised 1040, the 1040x, and a letter explaining what I was doing. This was advised to me by a CPA, who said it wasn't absolutely necessary, but would avoid any requests for more information. The result: no IRA response almost a year later, so I guess it was OK. Truly, I was just trying to save printing and postage costs. Big deal!
