Tax year overview does not reflect self-assessment calculations

Hello, I submitted my self-assessment form on 27th October - I am not self-employed but I'm required to file self-assessment due to the High Income Child Benefit Charge. My self-assessment calculations show that I am owed a tax repayment. However, the tax year summary overview on my online account, does not reflect these calculations and continues showing £0 for tax owed and £0 for tax repaymement due. Quick google search showed that the overview section should have updated within a few days of the self-assessment form being submitted. I have not received any information from HMRC regarding any issues with calculations or, indeed, anything at all. Has anyone encountered a similar issue? Thanks

Hi 
Once you submit your Self Assessment it can take up to 3 working days to process to HMRC records.
If you have submitted the tax return and the details have still not updated on your online account then you will need to contact HMRC to review.
Thank you.
