If you have voided a check into the current reporting period (Quarter) and there are no positive earnings in this period for this employee(s), these negative wages will not reduce the amounts on the Aatrix 941 report.
It is not unusual to void a check issued in a prior reporting period to the current reporting period. If this is done and there are no other wages for this employee, the Aatrix 941 report will not report the "negative" wages. The totals on the Aatrix 941 report will be higher than your Deposit Summary or 941 Preparation reports.
