Under Deductions and Credits tab, "your tax breaks", line 4 "income taxes paid" - where do the values for 2017 and 2018 come from?

If you scroll down past the Tax Breaks page on the Deductions and Credits screen to the Estimated and Other Taxes Paid.  Click Show More.  Then select Income Taxes Paid.  You will see a blue link that will give you a breakdown of the actual number for 2018.  See screenshots

But, that number summarizes ALL of the taxes you have paid either directly or through withholdings on Forms such as W2s, 1099s, etc for both your federal and state returns.  For example, that number would include both of your Federal and state withholdings.  It can also include local taxes, refunds applied to this year's taxes from a prior year, balances due from prior years that were paid in this year, and payments made with any extension you might file.

While it shows under Deductions and Credits, it’s actually just a summary number and not necessarily related to any particular deduction (some of it is not even a deduction - i.e. federal taxes withheld on your federal return).

 I can see for Oregon , my employeer placed ORSTTW 51,733.94 in box 14.  Turbo tax mistakenly added this to "taxes paid".    It does not impact the calculation of the actual taxes we owe.   Thanks!
