Even though the full amount shows up as income on the 1040 as income, if you have capital gains or qualified dividends the tax on line 11 is not taken from the tax table but is calculated separately from schedule D.  The tax will be calculated on the Qualified Dividends and Capital Gain Tax Worksheet.  It does not get filed with your return.  In the online version you need to save your return as a pdf file and include all worksheets to see it.

138,175 minus 5500 minus 24,000 = 108,7675 taxable income

Tax on that equals $15,787 before the Child Tax Credit.

Turbo tax is giving me tax payable as $15,587 which is $200 less than the tax table number as you have computed. Thanks.

Had to use the qualified dividends and capital tax worksheet, now it matches. Cool, turbo tax is always right.
