Self Assessment State Pension Entitled to but unclaimed

The online form states the amount you are 'entitled to' should be inserted. But I have not claimed the state pension yet, so do I have to declare the amount I would have received, had I claimed, or leave empty since I have NOT claimed and therefore not received? I am of an age to be able to claim. Thanks.

Hi ,
 

If you are not yet in receipt of the state pension then you would leave blank.

Thank you .
