Child Benefit one more week payment

Dear Home Office, I am filling my self assessment for tax year of 23-24, and one question asks how much child benefit my partner received. The form's calculator gives a figure automaticcally, based on the starting date (mid of 2023) and ending date (5/4/24) we received child benefit during the past tax year. However, the calculated figure in the form does not match the actual child benefit we received. The reason is we received a payment of child benefit on/around 29 March, i.e. the last payment we received for tax year of 23-24, and the next payment we received was near end of April, which falled into the new tax year of 24-25. The form calculated child benefit figure, however, added one more week of payment between 29/03 and 05/04, which we did not receive. So for the purpose of filling my SA, should I answer the question on how much child benefit we received for tax year 23-24 using the form calculated figure which adds one extra week of payment that we never received? Or should I put the actual payment we received which excludes the one week payment between 29/03 and 05/04? Thank you.
