Unfortunately, I don't have any advice, can only commiserate with our issues.  I went to do someone's 4th quarter reports and W-2's today (I have already processed a 2026 payroll for this client) only to discover that Jan-Apr was 2025 payroll and May-Dec was 2024 payroll.  WTF?  This is the second client I have had an issue with their EOY info being incorrect.  I do not have time to keep restoring an old backup for each client, reenter a couple weeks of payroll only to do the reports for the end of the Quarter/year.  I can agree with you that we should be due a refund or credit of some sort.  We are going to start looking into a different product because this is absolutely ridiculous.
