Received a 1099-R for survivor income benefit received. Is it taxable? What line is it reported on 1040?

Received payments during 2007 for death benefit from my father's disability insurance policy. Insurace company said it wasn't taxable and didn't withhold taxes. Box 2a is empty. Box 7 has code 4. Filing form 1040 and need to know boxes in which to report it. Can't get an accurate answer from anyone. Your help is greatly appreciated!
