Will I See a Stimulus Payment on my 2020 Tax Return?

In 2020 I was not eligible for a stimulus check because on my 2019 taxes I marked "someone can claim me as a dependent." Well, that was my first time filing my own taxes and I realize that was a mistake. I saw somewhere that when I file my 2020 taxes I will receive a stimulus payment because I never received one. Is this true? Will I receive stimulus money on my 2020 tax return in addition to whatever refund I am already getting?

 

Thank you!
