This is a user to user forum.  Nobody can see your income tax return, nobody can see your user screen.

Print out your entire income tax return and start going through it, line by line.  If you have last year's income tax return in paper form - and you really should - then do your line by line comparison between the two years as well.

Self Employment Taxes are a function of your Schedule C income and the mechanics of Schedule SE.  You should be able to answer your own question.
