SSA income is shown on "your income" page but is not included in total income in tax calculation , even though my income is well above the taxable threshold. How to fix?

Look at your Form 1040 to see the Social Security benefit taxable amount on Line 6b.

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.

Thanks.  That was helpful.
