I am sorry I confused the single Non dependent status with dependent one, below is correct:
As a dependent under the age of 65 you are required to file a tax return if any of the following apply -
1. Your unearned income was more than $1,100.
2. Your earned income was more than $12,200.
3. Your gross income was more than the larger of—
a. $1,100, or
b. Your earned income (up to $11,850) plus $350.
