The child is said by the Metro Nashville Police Department to have run to get help from a neighbour, who called 911. Investigators are currently waiting for autopsy results to determine her cause of death, but no foul play is suspected by police.
Dukureh was also known to Doja Cat fans after she appeared as Big Mama Thornton in the singer's music video for the soundtrack song Vegas.
She also joined the rapper, on stage earlier this year to sing the tune at Coachella.
Big Mama Thornton had a huge impact on the young Elvis, who made her song Hound Dog world famous with his 1956 cover.
Dukureh was renowned as a gospel singer in her hometown of Nashville before acting, and taught local kids.
Her role in Elvis was initially set to be off-screen, but she was later asked to appear in front of the camera.
She said about the role: "I knew to really pay tribute to her, I had to tap into myself, my own self-confidence, my own voice.
"Big Mama Thornton was very adamant that she only had her voice – no one could sing like her and she sang like no one. So I had to also embrace that as our approach to music."
She last month added she felt like she was "on cloud nine" amid acclaim for Elvis.
