Hi there, daytonabeach.
I have two options for you on how to reconcile the $1.00 difference. You can either record a difference to resolve the reconciliation or edit the invoice and add a line item with a negative amount (-1.00).
However, it's best to consult an accountant for you to reconcile it correctly.
You can also read this article that will help you adjust a reconciliation.
Feel free to drop your reply or post again if you have other questions.
