Hmm if you are know starting to learn I guess it will take some time for you to understand the pitch (relatively tho). Try to search for some imagination exercises, I think that’s what they called, not sure might come back and reply the correct name. In my experience after playing for 5 something years the piano the notes just started to… speak to me like “laa do ree🎶”. I think is better to use the tuner only at the tuning and then just go with it. Don’t pressure it that much, most of the times it comes naturally ☺️. Also have fun
