If I worked and am going to school full time, but let me daughter claim me why do I not qualify?

Because if you qualify as a dependent, even if you are not claimed as a dependent, and you are over 16 years old, you do not qualify for the Stimulus Payment.

If you earned more than $4200 during the year, your daughter cannot claim you as a dependent.

How much do you make from working? If it was more than $4200, in  2019, your daughter cannot claim you as  a dependent.  It doesn't matter how much support, she provided.  The income test, alone, disqualifies you.
