Ditto! Exact same error when trying to e-file. My form 7206 has lots of data entered, so I guess I can't just delete it. I paid for e-file, and now I get to spend at least $15 mailing 76 pages by certified mail. TurboTax should be refunding money to everyone who is affected by this coding mistake.
And where is this mystery reject code? The status page for my rejection only lists the exact message entered above.
