As the previous answer says, you don't have to panic. Most of what you've read about the big dangers of watching TV is very likely to be BS (see Why Most Published Research Findings Are False) If TV was that bad for children's language skills, we'd see a lot of muteness around
But of course I understand that you don't want your child to spend too much time in front of the TV and focus more on social interaction instead. That's great and, since you are the parent, you can decide how much time to dedicate to TV (or Youtube, or whatever) You don't have to be too drastic, either.
In short, don't panic. The fact that you are having this concern proves that you are already better than the average parent. Keep doing what you do and get in charge of your child's personal development and education.
But TV and media can also have a good impact on her if you use those ressources wisely at, for instance, learning a second language or showing stories that fit moral values you want to teach her
