Toilet Tank supply valve condition

[CluelessHomeowner]

is this normal ? I check the other 2 toilets and this is the only one

I'm guessing i need a new valve? I don't know if it's 1/2 or 3/4 :? I'll need to shut off the cold water line outside of the house and turn on the a cold faucet before working on this ?

I think it's just a compression fitting so a wrench, drag and some container for the job ??

Yes! That is 5/8 compression on the pipe from wall. pull the old ferrule/olive and nut off. don't try and reuse it.
Sometimes the ferrule crushes the pipe and is hard to get off.
You can use a fine tooth hacksaw blade and cut the pipe right behind the ferrule. You have extra pipe sticking oit of the wall. Those 1/4 turn brasscraft you get at HD are crap. The stems are small and break off easy. I use DAHL valves.

I found out that there's a class action lawsuit against Brasscraft regarding the valves you mentioned
