I entered $29,016 as my Social Security income on data entry page, but it changes to $24,664 on the final income review page. Why the change?

The amount shown on the final income review page is considering only the taxable amount of the Social Security income that you received for the year. 

Depending on your other income reported on your return, up to 85% of Social Security income may be taxable.  $24,664 is 85% of $29,016.
