Incorrect 941 filed with IRS showing Balance Due!

My client has Workforce Payroll. They are enrolled into automated taxes and payments. I just reviewed the 2026 Q2 941 and was shocked to see a “balance due” on the 941. I confirmed that Intuit drafted all tax deposits from my client’s bank account for the entire quarter and the reporting in QBO shows that the funds were paid to the IRS. I called support and they tried to re-generate the 941 but with no success. We discovered that the 941 payment total did not include the last tax deposit that was made for the quarter. As such, it was clearly a QBO system error that didn’t calculate the correct payment amount on the 941. There was no follow-up as to why this happened and I just found out it happened to another client. And since our subscription doesn’t include amendments, I was told I would need to file the amendment myself.

My questions are: 1) why would Intuit not research/fix/communicate an error that impacts filings with the federal government? 2) when it is clear that the system failed and was demonstrated with your own support folks, why would you not make us whole by correcting your own error and 3) how am I supposed to continue to support 150+ payroll clients using your (increasingly expensive) software application that is sabotaging tax filings and creating a ton of manual work?
