TurboTax can't provide a simple summary of the calculation of the tax on Form 1040 line 16 because the calculation is very complex. The IRS instructions for line 16 in the Form 1040 Instructions are more than a full page of text plus two worksheets, and they reference a number of other forms and worksheets in other IRS documents. There are seven different methods that can be used to calculate the tax, depending on what is in the tax return. There's no simple way to summarize all of that.
No one said that the Tax Smart Worksheet in TurboTax shows you the calculation of the tax. All it does is tell you which one of the 7 methods was used. The Tax Smart Worksheet is not included in the PDF of your tax return. In the desktop TurboTax software you can see it in forms mode, and save it to a PDF if you want to. There is no way to see the Tax Smart Worksheet in TurboTax Online. A "Smart Worksheet" in TurboTax is not a separate form or worksheet. It's a box embedded in another form or worksheet. The Tax Smart Worksheet is between lines 15 and 16 in the first section of the "Form 1040 or Form 1040-SR Worksheet."
