Should I see an amended amount immediately in the successive years download *.tax2016 if I am working on *.tax2017? How do I bring forward losses if they don't update?

Only if you transferred in from the prior year amended return.  You can only transfer into a new blank return.  If you need to amend the next year you have to start with the original filed return and manually make the changes from the prior year amended return,
