Hi
If you are unable to pass the verification questions being asked you will need to complete a paper tax return for 22/23.
You will need to request the SA100 from our Self Assessment department. You can do this in writing or by clicking 'Ask HMRC Online' and asking to speak with an adviser.
You will then be put in the queue to speak with a Webchat adviser. You can find our contact details here

Thank you
