Why does the IRS tax table show a lower amount as tax, than what Turbo tax calculated?

Usually it's the other way around, Turbo Tax is lower.  

There are like 7 different ways to calculate the tax.
It depends what kind of income you have. Even though the full amount shows up in the total income on the 1040 line 7, 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 the worksheets to see it.

Thank you for your reply - I tried to edit my question to add more details

What line is the $9,021 on?  The tax should be on line 16.  Then you might have some other taxes on lines 17-23.  Like the 10% Early Withdrawal Penalty on IRA & 401k etc.  or  self employment tax or something else.  Check all the lines on your return.  Which don't you understand?  Do the credits, withholdings and payments look right?  

I haven't paid for it yet, so it will not show me the entire 1040 form. I am using the Deluxe online version.

When I click on "Explain my Taxes" at the top, it brings up a section on the right of the screen and here is what it shows:

Yeah you really need to look at your tax return, not a summary or review screen.  You should be able to see enough of your return doing a preview

Before filing you can preview the 1040 or print the whole return

No, that is not true. When I follow your linked instructions and go to Print Center and click on Preview, I see

You can view your Form 1040 plus Schedules 1, 2 and 3 at any time using the online editions. Click on Tax Tools on the left side of the online program screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.

Thank you! I see now that it says

Line 16: $7345

Line 17: 

Amount from Schedule 2, line 3: $1676

The excess doesn't come from the adding of the columns.  Instead, it relates to how much of the net premium tax credit exceeds the allowed amount based on your income and family size.
