Hi Deb!
You will enter the cheque as normal, using the date that was actually used on the cheque. Expense it to the account you normally would. When you reconcile your bank, you will leave the item unchecked. This will carry into January, and if the item clears in January, you will be able to check it at that time. The expense, though, belongs in 2016, so use the cheque date to make the entry.
I hope this helps!
