QB Issue Resolution:

The Banking is one lump from Equity; you send the money to the investment broker holding your account. You don’t have two parts; there is no Deduction from the employee’s payroll, because you are not your own employee and you don’t get paid gross wages from payroll and there cannot be a deduction from what does not exist. That part of the Computation doesn’t apply to you. Your part is a different section of the provision.
