Will the 2020 or later W-4 checkbox impact records before 2020

Will checking 2020 or later W-4 in Deduction and Benefit Master and Employee Deductions impact records before 2020?

• Payroll
• Deduction and Benefit Master
• Employee Deductions

• Checking 2020 or later W-4 in the Deduction and Benefit Master will not impact Employee Deduction records that currently exist.
  • This is used to default how new records get added.
  • If this field is checked, all new records added under that deduction in Employee Deductions will have 2020 or later W-4 checked.
