This issue can arise due to various reasons such as incorrect bank account information, expired payroll subscriptions, or connectivity issues with the Intuit servers. To troubleshoot this problem, start by verifying that your QuickBooks software is up-to-date and that your payroll subscription is active and properly configured. Check the bank account details entered for direct deposit to ensure they are accurate and up-to-date. Additionally, ensure that there are no issues with your internet connection or firewall settings that could be blocking QuickBooks from connecting to Intuit servers. If the problem persists, contacting QuickBooks support or checking their online resources for specific troubleshooting steps can provide further assistance in resolving direct deposit issues promptly.
