Laravel 5.8 PDF upload

for my website I need a form which includes a file upload for PDF files, but I'm new to these and don't really know how to do it.

This is what I got so far, but keep getting: "Too few arguments to function App\Http\Controllers\FileController::create(), 0 passed and exactly 1 expected"

Controller:

<?php

namespace App\Http\Controllers;

use App\User;
use App\Payment;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;

class FileController extends Controller
{
    public function index(){

    $users = User::all();
    return view('fileupload.create', compact('users'));
}

protected function create(array $data)
{
    $request = app('request');
    if($request->hasfile('file')){
        $file = $request->file('file');
        $filename = $file['filename']->getClientOriginalExtension();
        Storage::make($file)->save( public_path('/storage/loonstrookjes/' . $filename) );
        dd($filename);

    }


    return Payment::create([
        'file_name' => $filename,
        'file_path' => '/storage/loonstrookjes/',
        'user_id' => $data['employee'],
    ]);

    return route('fileupload.create');
}

}

Model User:

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Kyslik\ColumnSortable\Sortable;

class User extends Authenticatable
{
    use Notifiable;
    use Sortable;
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $table = 'users';

    protected $fillable = [
        'username', 'first_name', 'last_name', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];
}

Model Payment:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Payment extends Model
{
    protected $table = 'payment_list';

    protected $fillable = [
        'user_id', 'file_name', 'file_path'
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'id', 'file_name', 'file_path'
    ];
}

            </div>

@endsection

I hope someone can help me find out what's wrong or a better way to do this. Thank you in advance!!
