Ok i think now we ready to see the whole picture and resolve the
paradox.
For clarity i will assume that A is on earth and not moving anywhere
and B is moving from A to the nearby star 8 light years away with a
speed of 0.8c, then B turns around and returns back to A with the same
speed of 0.8c.

Now lets examine what each of them actually sees:
1) A for the span of 18 years sees how B is moving away to the
distance of 8 l.y.
after 18 years A can see that B has finally reached the distant star
and that it took 6 years of B's life ( remember B processes where 3
times slower hence 18/3=6 years life to move those 8 light years )
now B turns back and flies back.
It will take 2 years of A's life to see how B comes back from 8l.y
distance. This will take another 6 years of B life ( 2years*3=6years
cause they approach each other and see life 3x faster)

So in total of 18+2=20 A's life years he saw the B's adventure and it
took 6+6=12 years of B's life. If A was monitoring with big enough
telescope the clocks onboard of B rocket then A indeed whould see how
the clocks ticked exactly 12 years.

2) now lets examine what B in his rocket sees about A.
for the 6 years of B life he sees how A spends 2 years ( 6/3=2 cause
they moving away from each other)
now it is time to turn back
on the way back which lasts another 6 years B sees how A lives 18
years (6*3=18 cause of aproach)
so after 12 years of B's life he meets A who is 20 years older now
