You don't have to report form 1099-A for your main home. A personal residence sold at a loss (and that's what
foreclosure/abandonment on form 1099-A usually is) is not reported on a federal return because personal
losses are not tax deductible.
Keep 1099-A for your records though. You may receive form 1099-C from the lender for the
cancellation of the debt, the 1099-C would be reported (Form 1099-C may come in
future years) in the year you actually receive it. Since the form 1099-A does not indicate the debt forgiven,
please wait until you receive form 1099-C to report forgiven debt.
