baby chewing

my daughter is 11 months and she's not chewing correctly/ enough. yesterday I made some potatoes, they were really soft and she started choking! she also had a rice snack and started choking again!! I don't think she'll be ready for cake on her 1st birthday 😔 as I gave her a crumb of cake last week and she started choking.... What kind of food should I give her? she refuses baby food. I'm not sure if it's bc she's teething or what. please help. should I start giving her food that u would start off a 6 month old on..? edit: I started her off on baby food and she would eat it good. but now she doesn't want it at all. I would give her mashed potatoes, mashed avocados (she still eats fine), some Ramon noodles but it seems as if she forgot how to chew? she's really choking not gagging. She turns red and really scares me. She usually has 1 or 2 bites of baby cereal each morning. I offered her baby oatmeal mixed with banana baby food and she does not want to eat at all. not even a bite. I feel like it's bc she's teething. I think she's getting a tooth on top. but either way, she's been choking on food a lot lately..
