Please be specific. I‘m stupid with this kind of stuff.
There should be a tab you have to depress. Turn the wiper like they said to form a T and slid it off the stud the J hook clips onto. The new ones should just click on. Or take it to the autoparts store you purcheced them from and they'll put them on and even show you what they had to do to install or remove them so you'll know in the future.
Taking Off Windshield Wipers
I'm going to call it a U for explanation sake. Just inside the open end of the U should be a small tab attached to the wiper. bend it away from the rubber part of the wiper and slide it out of the U or J at the same time. the new onee shold just click into place. You can look at the new one to see if you see the tab. also there should be directions with the new one.
