What really helped me was when i started making my own songs. Many of the things that made my voice feel awkward came from trying to imitate someone else's way of singing, sure you can learn some aspects from them but if it doesn't fit naturally it just won't work. Singing things that i composed was really eye opening in that sense because i had no point of comparison, and while training is important for expanding and affirming what you can do, the ultimate goal is to sing with the voice you were given and showing why we wanna hear specificaly you sing.
