Why does Turbo Tax say my taxes withheld on my W-2 is only $334 when Federal income, Social Security and Medicare taxes withheld add up to over $460? What am I missing?

Only your federal wages and  federal income taxes withheld are reported on a tax return as shown on your W-2 in box 1 and box 2.

Federal tax withholding is separate from withholding for Social Security and Medicare taxes.  The Federal tax withheld is the payment you make towards the tax due on your return. Social Security and Medicare taxes are payments made towards your retirement benefits.

Okay thank you for helping me. I'm pretty tax dumb haha. Thanks again.
