After you file

First of all, I want to say thank you for your comment. But can you help me to answer this question? It has been 21 days since I filed my 2019 tax return. My Turbotax account states that 04/26/2020, I can receive my tax refund, but nothing has changed as of now. And I worked a part-time job and made less than $5000 based on my 2019 tax return. According to what you have said, Why didn't I receive my stimulus check yet?
