Hello Raina Abadilla,To report your hacked Instagram account, use a web browser to go directly to the following web page, and follow the instructions there:Help Center - Privacy and Safety Center - Report Something - Hacked AccountsBut note that the behavior you observe within the app may indicated that the app is hacked, and your account might actually be fine; if somebody compromised your app, then by filling out your password there, you are actually leaking your password to that person, and not to Instagram.
