Maybe you can call sage support and they can remote in with you and look at what you have.   It is probably something really simple.

Go to Maintain Employees and bring up that employee. Go to the Employee Fields tab and find the line for the 401k deduction. Is the "Use Defaults" box checked? If it is not checked, click the Adjust button on the 401k line and make sure that Gross is the only line that has a check in the Use column.

If the "Use Defaults" box was checked, go to the Maintain menu > Default Information > Employees, then go to the Employee Fields tab and do the same thing there.

Thank you this did it. The "using defaults" was checked. But it looks like someone had checked pretax and mileage. This corrected the 401k contribution to the correct amount. But it also changed the fed income tax line withheld. It went down a few cents. So I guess each employees was having more withheld than they should. An I was mistaken this actually affected more people than I thought.  I'm a bit embarrassed that I did not catch this sooner. But looking at past paychecks this has been happening way before my time. I guess I should tell the boss and see if we need to talk to the accountant.
