Plan ahead, clean out the refrigerator and make room for leftovers several days before the holiday feast.
Leftovers should be stored in the refrigerator within 2 hours after cooking is completed. Why just 2 hours? Because bacteria that cause food poisoning can multiply to undesirable levels on perishable foods left at room temperature for longer than that.
Large quantities should be divided into smaller portions and stored in several shallow containers. Food in small amounts will chill faster keeping it safer and fresher.
If a large amount of turkey is left, consider freezing some for later use. Do not wait until the turkey has been in the refrigerator for 4 days to freeze it. Freezing will not improve the quality of the turkey. If the turkey is frozen while it is fresh the quality will be better upon defrosting.
