If your only Social Security tax paid is that calculated on Schedule SE, your Social Security wages are the amount listed on short Schedule SE line 4 or long Schedule SE line 4c, but limited to the Social Security wage base for the particular year (the dollar threshold shown in the instruction for line 5 of short Schedule SE).
Regardless of your sources of wages, for years where your wages are greater than the Social Security wage base, the Taxed Medicare Earnings shown will be greater than the Taxed Social Security Earnings shown.
