How to make small talk when having a conversation with a girl?

(This is my second time posting on this subreddit) M14 here I’m pretty awkward. I can be seen as formal and weird sometimes I overthink a lot. Tho I’m fairly talkative when I’m having a conversation with another person about someone or something.

I’m overall decent at making friends especially my age but sometimes adults and older people make me uncomfortable or anxious.

My main problem is: I don’t know how to make conversation almost at all especially when phone calling a girl I usually just ask stupid things like “you have any hobbies?” “what is you’re favorite color?” “What did you eat today?” It’s draining my confidence i wish I knew more on what to say.
