I too received a form 1099-A and am confused about how this is going to affect my return! I have not received a 1099-C. The outstanding principal balance was $271,593. And FMV is noted as $284,104. However the house sold for $170,500. Box 5 is not checked. This was my primary residence in Arizona. Is the tax liability the difference between the outstanding loan amount and FMV or the amount it was sold for? Thanks for all the good information!
