How can I see the calculations to compare to a manually prepared form I did? I believe the Turbo Tax calculation is incorrect.

Where can I find how Turbo tax calculated the taxable social security income?

You must pay the TT fees in order to view worksheets.

The Social Security Benefits Worksheet is the one you would need to look at after you print out your return.  You should check your entries under the Social Security section first, though.
