Why am I still paying for my 32 year old daughter?

I am currently in receipt of income support due to being on carers allowance.i had to check my IS the other day I inrecieved a very low payment. I was notified that I’m still paying the csa 10.00 per week out of my IS for my 32 year old daughters surely this can’t be right when I was working I was lucky if i was left with 10.00 a month to live on as they took everything including my pay of 1000.00 over the mileniumn period of the year 2000.inseem to have been paying for over 30 years. I need to know what’s going on.
