Help With Tax

Hello everyone,Im looking at doing my first ever tax return for my ebay business.I know I have left it a bit late,but have been in and out of hospital for the past month.Where do I even start with doing this tax ? If I was to go to get professional help,what information will they require ? Most of my items are dropshipped from china also,I really have no idea where to start.Has anyone else recently done their tax and could give me some info ?  thanks for reading
