Dependent tax liability

[Michaelsmomjoel]

My dependent has w-2 @ 3200  self employment of 5900 -(with deductions  4600 )and unemployment of 17k with taxes taken out.

i was using turbo tax and everything was looking good he owed about 600.00 for fed & state and then got to the add the person claiming you and it wanted our taxable income I put  85k in and it shot my dependent owing almost 3200 for fed and it said the reason why was on the  self employment 

why would he owe more after i entered our taxable income ? This makes no sense at all.

He is 19 

The w-2 and UI had taxes taken out, the self employment was about 5 k , it saying almost 3200 for fed owed on 5 k income ! Does this sound right ?
