I uploaded my (only) W2 to TT. The "Income Taxes Paid" shown by TT doesn't add up to any combination of my taxes on W2. How does TT calculate my "Income Taxes Paid?" Thx

I didn't have any other income, just 1x full-time job. There are four types of taxes shown on my W2 - federal, state, SS, and medicare.  No combination of them adds up to the amount shown by TurboTax as "Income Taxes Paid."
