Exempt from federal Employee's were allowed to edit section 2-4 in W-4 form in employee self service

Refined issue description

When testing federal tax elections in Self Service for a test worker, an exemption from federal income tax withholding was selected in accordance with the Form W‑4 instructions, which specify that an exempt employee should complete only identification and signature steps and no other withholding adjustments. However, Self Service continues to permit entry in all steps of the federal tax election (including sections corresponding to steps 2–4 on Form W‑4), and the concern is that these additional inputs may be processed along with the exempt election, potentially causing either unintended federal tax withholding or tax calculation errors.​
