Hi, @Pmull001 thank you for reaching out to our online community.
You can try to void your check using the following information.
To void a check from a closed/prior period: Enter a deposit in the current period for the total amount and post it to principal & interest accounts. Put in the description the Check #s that you are voiding. This puts the amount back in the checking account.
Then, when you reconcile the bank account check the checks being voided & the deposit as being cleared.
Hope this works as a solution and if you still encounter issues don't hesitate to reach out, we are always happy to help.
