Employees and payroll

I was able to create a new deduction and modify the amounts so that the wages tie out. Additionally, I also completed the remaining payroll setup taxes, etc. However I am now faced with another issue that I can't seem to resolve. Some of the tax exemption information for my employees did not import into the online system. When I try to update that information I am receiving an object not found message and cannot save the updates. Our company also pays the full cost of Massachusetts Paid Medical and Family Leave which is appearing but I am wondering if that is causing the issue. Could you please let me know how to resolve this problem? I would like to start paying employees through the online payroll but without this information I cannot do so correctly. Thank you for your time and assistance.
