Vocal Coaching: Learning to Pitch (Singing)

I'm writing to enquire about online vocal coaching / singing lessons.

I sing in a band and have gigged extensively for about 3 years now, we were invited for a session with a producer and he basically said I need to learn how to pitch when I sing and get some professional help. He said its almost like I'm tone deaf, which isn't the case because I can recognise notes, but I just cant control my voice to make them. It's kind of atonal when I sing? I need to learn how to pitch.

Anyway, I wondered if this was something you think we could fix through singing lessons and whether you can do them online through the coronavirus situation?
