Tax Year Prior to 2020: So I owe $675. would it be best to raise my 401 deduction by 2% or have $75.00 more FWT taken out each month?

I can't give you financial advice. However, I can tell you that increasing your contribution to your 401(k) will reduce your overall taxable income.  Plus, the money you invest goes toward your own retirement.
