Okay so I have a question about what I should do if my employer screwed up on my W-4 for 2019. I had entered in zero when claiming dependents and put down that I wanted an extra $10 withheld from each paycheck. Come this tax season when I got my W2 it showed that I only had $100 in federal taxes taken out, I didn't think anything of it until I went to file my return. After completing the return using TurboTax the app told me that I owed almost $500 this is where I started to notice things were wrong can anyone please help with information on what I should do to fix this
