When did Celts settle in Spain?

[Peterski]

YFull estimates the TMRCA of my subclade (which exists in Poland and in Spain) as 900 BC:

Another website - YTree - estimates the TMRCA of one subclade about this level as 247 AD:

Maybe I will transfer my data to YTree as well.

Question is, what movements of people between these two areas took place after 900 BC?

There are also Czechs near the root of this branch:

No idea, maybe because they were accepted by the locals and liked the places there?
We could ask ourselves why Welsh,Scottish,Bretton Celts settled in Britain while Irish Celts settled in Ireland and why these Iberian Celts settled in Iberia?
While the Bretton Celts also settled in NW France?
Maybe there were also different migration routes, in those times, it was not like as it is in our times, getting from more North Europe some thousands of kilometers Westwards might have been easier, than taking from same point of Europe some hundreds of kilometers Southwards.

It seems the British and Irish Kelts migration route passed through Netherlands, Northern France and from there, they went to Britain.
While these Iberian Kelts took a more Southward route, maybe they came over the sea, or who knows, from North Italy, to South France and from there, they passed in Iberia.

I asked WHEN not why, though.

But those are suppositions and you also need to know what kind of Celts you are asking about, seems were different type of Kelts that settled in Iberia.
