I think the source of the problem is something called "IRA Worksheet" in the "Forms in My Return" section, though the head of the document says it is called "IRA Deduction Worksheet." I think the problem is: "Fraction of line 13 that is deductible." is 0.600 for me. I don't know where this comes from. This seems to be a non-standard form. There is only one Google result for "Fraction of line 13 that is deductible," and it seems to be an upload of someone's TurboTax form. I want that to be 0, I told TT in the wizard I want that to be 0, but the dollar amounts on line 15 and 16 that result from multiplying line 13 by 0.600 seems to be where the problem on my IRA Contributions Worksheet is coming from.
