Icici late bill payment

[napster003]

So I have 2 icici amazon credit card( one mine and one my dad's)
Both had their due date on 30 September but due to being busy in home renovation I totally forgot to pay both.
Just paid bill 25k and 4k for both cards on 1st October ( one day late). And both reflected in bank website.

Will I be charges late payment fee and interest ? And will it affect credit score?

This is my first late payment for a credit card
