Placement of income (1099)

Ok guys only taxable income I have is a 1099 (s), I have zero tax because of the deductions. But if I just put the 1099's in business income I get a 4500 self employment tax. Up until now I always put everything in personal income. Is that the correct way cause I grossed 61k and had write offs of 50k but it says I owe 4500 cause of S.E.T. (Uber driver)
