I got the fake apple email to confirm my purchase and accidentally provided some of my personal information on their site. What can I do?

I opened an email to looks like from real Apple which confirms my recent purchase (unknown game) with my Apple ID which is game. It comes with pdf and has a link to cancel that purchase. I accidentally went to that site which really looks like an Apple again and provided some of my personal information. I realized something is weird and stopped. I did not go to the end or submit anything , but I input some of my personal information. I checked my purchase history on my iphone which I did not know this feature and realized that I never purchased that game which was shown on the email. So I was fished. I changed my apple password. But what should I do next? I input the information on my iphone.
