Get your taxes done using TurboTax

When using the calculator tool, it shows a negative amount in the 2025 estimated payment - does this mean that is how much I will owe next year?  

 

Do I change the "your paycheck impact" to adjust the extra tax to withhold per pay period?  Meaning they will continue to take out the same as what they are currently taking out PLUS this amount?  Or will the amount taken out be only this new amount?
