Enter the 1099-C on TurboTax as it is on the paper form. Box 2 is amount of debt discharged and is the amount taxable unless it otherwise qualifies for
an exclusion or an exception. Some exceptions are regarding mortgage debt,
bankruptcy and insolvency. The difference of the debt and the sale is irrelevant.

other) and then click Continue.
