Hello there, iwillplumbingandheating. This error happens because QuickBooks is trying to protect your finalized records from changes. When a closing date is set, the system blocks any new transactions, including paychecks, from being posted on or before that specific day.
To fix this, navigate to your Account and settings > Advanced. In the Accounting section, temporarily change or remove the closing date.
Once the date is adjusted to a day before your paycheck's date, you can successfully sync your payroll data. Just remember to re-enable that closing date lock afterward to keep your past books secure and accurate.
