I submitted claim to UC, yet I received Child Tax Credit

Hello,

I received my managed migration letter to UC.
I submitted my claim online with proof of ID, housing cost etc.

My child tax credit should have been stopped yes it has been paid.

Should I call Child Tax Credit to tell to stop it?

Should I also contact Esa and ask them to stop it?

I thought Childs Tax Credit and Esa was stopping of its own accord.

I appreciate any help.
Thank you.
Best wishes

Hello David,
I called them because of the one payment child tax credit after I submitted my claim.
But they told me it is not 1 week but 2 that were overpaid as they were issued at around the date I submitted my claim, and also that the payment were issued in advance not in arrears.
But they will send me a letter to sort it out, but they would not tell me anymore.
Thank you.
Best wishes
