Laravel Seeder using Factory Faker having Relation of Relation

Question

Below are the Tables with fiddle link

TableA

id	col1	col2
1	1	1

TableB

id	tableA_id	count
1	1	10

TableC

id	tableB_id	quantity
1	1	5
2	1	5

I have a three table with relation of each other.

TableA->TableB->TableC
              ->TableC    

count column in TableB->count is sum of TableC->quantity relation.

How Can I seed the tables using a Laravel Factory Faker?

What I have tried?

TableASeeder

Method:1

public function run()

 $qty = fake()->randomElement([100, 150,200,250,300,400]);
        $tbla = TableA::factory()->has(TableB::factory()->count(2)->state([
            'count' => $qty,
        ])
        ->has(TableC::factory()->count(2)->state([
            'quantity' => round($qty/2),
        ])))->create();}

Method:1 code I am getting below error message

Call to undefined method App\Models\TableB::tableb()  

Method:2

public function run()
 $event = TableA::factory()
        ->afterCreating(function ($tba) use($qty) {
             
            TableB::factory()->for($tba)->state([
                'count' => $qty,
            ])->afterCreating(function($tbb) use($qty){
                TableC::factory()->for($tbb)->state([
                    'quantity' => round($qty/2),
                ])->count(2)->create();
            })->count(2)->create();
        })->create();

Method:2 code I am getting below error message

Call to undefined method 6Illuminate\Database\Eloquent\Relations\HasOne::getOwnerKeyName()  

When I run the above seeder TableASeeder it creates a TableA Record and Two TableB Records

Now I need to seed TableC which is two records each with quantity sum equal to TableB->count in the above case it should be 10.
