1 year old won’t eat

My son hasn’t ever been interested in solids. He will eat his preferred foods such as Cheerios and such. I try to get him to eat solids, but he refuses. I will get him to try new things by sneaking it in his mouth and he just gags on it so much he ends up throwing up. I’m at a complete loss, he will be 14 months at the end of this month and I feel like I failed him and failed as a parent. He absolutely hates it when I come towards his mouth with a spoon or fork, he will do it himself but not with any food on it. We tried going to the feeding specialist but with this virus stuff going on they said they were only allowed to do video appointments, but that was a waste because my son is more interested in the phone while he’s in his high chair than he is in his food. Any advice would be appreciated, I’m just so stressed out.
