I like to use various online tax calculators to see my estimated taxes for the year, like this one from TurboTax:
https://turbotax.intuit.com/tax-tools/calculators/taxcaster/
One of the questions is:
"How much was withheld for federal taxes for 2023 (including unemployment)?"
Is that the value of ONLY Box 2 in my W2? Or should the answer also include the values of Box 4 (ss taxes withheld) and Box 6 (Medicare taxes withheld)?
Thank you.
