12 month old won’t eat !! Plz help

Hello everyone. I have a newly turned one year old and meal times are the worst. Firstly, I am terrified of giving her pieces bcuz of how much she gags . I’m afraid of her choking. So mostly her food is still mushy purées.

She hates sitting In her High chair. It has gotten so bad that I have to use an iPhone for music. Then I stoped that. Now I have to let her play on her Mat while giving her spoons of food. I really don’t know what else to do cuz she’s hungry for sure .. she literally screamsssss like shes in agony
