Self assessment - incorrect tax code/personal allowance

I am trying to complete my tax return but the form is assuming that my personal allowance is £12,570 whereas it’s actually £13,820 as I receive an uplift from my husband’s allowance. Please could you advise as to how to rectify this as it’s resulting in an inaccurate calculation. Thank you.

Hi

If you receive the marriage allowance transfer from your husband you do not need to declare this on your tax return.
Once we receive your Self Assessment tax return the system will pick up the transfer and amend the calculation. 

Thank you
