US Payroll: IT0210 vs IT0234

Hi Experts,

I wanted to know the difference between Additional Withholding field in IT0210

versus the Voluntary Withholding % field in IT0234 under Arizona Withholdings.

I was trying to create a record in IT0210 and allot an amt in Additional Withholding field. However this field was no editable.

Can you please let me know which field should we use to enter

Additional Withholdings ?

Regards,

Somdeb.
