Move to Universal Credit

Hi, I have now received a message from UC to say I need to provide name, address, telephone number and date of birth of my carer, before I can be considered for the transitional element of SDP. I was originally told that I would automatically receive it.
My adult children share my care between them and feel this request is a bit intrusive.
Is information obligatory?
Many thanks

I sent them a message regarding their information request, but, 2 days later, they haven't responded

I did send another message earlier this morning.
Just to confirm. Am I required to give them my carers information in order to receive the protected SDP?
Many thanks David
