If you made an error that requires a Form IL-941-X and you made the same reporting error on your return and your employee's Form W-2 or payee's Form 1099 or W-2G, you must also provide your employee or payee with a Form W-2c or corrected Form 1099 or W-2G, and attach copies to your Form IL-941-X.
Beginning in 2024, the IRS allows electronic filing of Form 941-X as part of Modernized e-File (MeF). However, only corrections for the 2024 tax year could be e-filed.
When you discover an error on a previously filed Form 941, you must: Correct that error using Form 941-X; File a separate Form 941-X for each Form 941 that you're correcting; and. Generally, file Form 941-X separately. Don't file Form 941-X with Form 941.

First, I recommend reaching out to your employer's human resources or payroll department immediately. Inform them about the error in your W-4 form and the subsequent over-withholding of federal taxes. They should be able to assist you in rectifying the situation.
Taxpayers use a Form 940 for correcting a previously filed return by checking the amended return box in the top right corner of the Form 940. Employers should use the corresponding "X" forms listed below to correct employment tax errors as soon as they are discovered.
Reminder: If you file Form 941-X to claim the Employee Retention Credit, you must reduce your deduction for wages by the amount of the credit for that same tax period. Therefore, you may need to amend your income tax return (for example, Forms 1040, 1065, 1120, etc.) to reflect that reduced deduction.
Use Form 1040-X, Amended U.S. Individual Income Tax Return, and follow the instructions. You should amend your return if you reported certain items incorrectly on the original return, such as filing status, dependents, total income, deductions or credits.
