Self Assessment not found in Personal Tax account

I have created my personal tax account and registered for self assessment with UTR. When I login my personal tax account, I cannot find the "Self Assessment" option for me to submit my tax return. I and my husband applied our UTR and registered our personal tax account at the same time. But my husband's account has the option for "Self Assessment" but I don't. What can I do now ?

Hi,
 

If you have completed Self Assessment before you will have another User ID that is linked to Self Assessment. If you have not filed online before, please contact our helpline : Self Assessment: general enquiries   . Thank you.
