Paper return -how long to process and receive calculation

I can see on the web page that my paper return for 2021 - 2022 was received on 3rd March 2023. How long does it take to get a calculation? I have filled in SA100 SA102 and SA109 (I moved to Abu Dhabi in January 2022). I also filed a late penalty appeal which i think has been accepted. When can I expect a calculation - it says 'in progress' been nearly 8 weeks. When can i expect a reply section is set up for the next year in the algorithm. SO to summarise - how long until i get a response re a clalculation?

Hi,

We are unable to provide a timescale for processing your return. Our post is dealt with in date order and there is a backlog at present.

Thank you.
