Blended tax rate of 38.6% and only 52k of taxable income/self employed…what!!

Hi, we are showing 123k overall income this year all going under our self employment. After deductions our taxable income is 52k. Then Turbo Tax is showing a blended tax rate of 38.6! Which comes to 14k in taxes owed. Does this seem right? 38% is a way different tax bracket than our income or am I mistaken? Thank you, learning here!
