Just update your import

from: import kotlinx.android.parcel.Parcelize

to the: import kotlinx.parcelize.Parcelize

With Groovy

build.gradle (project level)

dependencies {
    // .... project level dependencies
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files

    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.20-RC"
}

build.gradle (app level)

plugins {
    ...
    id 'kotlin-parcelize'
}

and the data class

import android.os.Parcelable
import kotlinx.parcelize.Parcelize

@Parcelize
class User(
    val firstName: String, 
    val lastName: String, 
    val age: Int
): Parcelable
