That might be a bug in TurboTax. As I understand it, I should report nondeductible IRA contributions on Form 8606 whether or not I received a 1099-R. I was able to get around this problem by temporarily adding my name to one of my wife's 1099-R forms. I was then able to enter my IRA basis, then I fixed the name on the modified 1099-R. Unless I'm misunderstanding something, this work-around should not be necessary.
