Amendment to change dependent? How to file and will it affect stimulus?

A different filing service filed me as "dependent" because I am a college student.

 

  • I have provided 100% of my own support.
  • I live alone.
  • 21 years old. Full time job. Student.
  • Verified I was not claimed by either parent.

Block is saying well, because I'm a student and a full time worker I don't qualify. I am the only one supporting myself.

 

On Turbotax, the e-file questionnaire shows I am not a dependent.

 

How do I fix this? Will I still receive a stimulus check from the IRS if I file an amendment? Should I file through the original filing or use an amendment from TurboTax?

 

Thank you. Please, please help me.
