Filled wrong address and name in yt adsense.

I was signing up for adsense and there was already filled information of my friend there and I was trying to change that but somehow I clicked on continue button.
Now it is showing “in progress”

Can I change the details according to myself later?

I'd contact them asap to prevent any type of issues.
I think once you submit the info you can't re-edit it.

Leave it for now, once it's active - you can change it this way; https://support.google.com/adsense/answer/2628816?hl=en
