Where do I find a work sheet that shows the calculation of line 15 form 1040?

Line 15 is taxable income.  It is just the total of lines 1-14.  Do you not understand a line above?

Do you mean the tax on line 16?  

If you have capital gains or qualified dividends the tax 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.

There is no worksheet for Form 1040 Line 15.

Line 15 is calculated by subtracting Line 14 from Line 11.

Line 14 is the sum of Line 12c and Line 13

Line 12c is the sum of Line 12a and Line 12b

Line 13 Is Qualified Business Income deduction from Form 8995 or Form 8995A (if applicable)

Line 11 is the Adjusted Gross Income - Line 10 subtracted from Line 9

Line 10 is adjustments to income from Schedule 1 Line 26

Line 9 is Total Income from the sum of Lines 1, 2b, 3b, 4b, 5b, 6b, 7 and 8
