I should stop trying to come up with workarounds and instead just submit a bug report. How should I submit a bug report? Is there a way that other people can support a bug report.?
I think that the desired behavior is TurboTax should import a previous year's return, including forms and Supporting Details, as it does now. The import should blank out dollar amounts, as it does now. So I suspect no changes would be required to the import process. When amounts are being added together, if all the amounts being summed are blank, the sum should be blank. I don't know of any instance where this is violated, so I suspect no changes would be required here either. The only change necessary would be how blanks are transferred from one form to another. If the amount field being transferred is blank, the field to which it is transferred should be made blank (not set to 0.00). The one example I have of where this violated is the transfer of the total from a Supporting Details form to Box 1 of a 1099-INT (but there be other cases where this happens).
