What do the tax numbers mean on an amended return? Is it the net change in taxes btwn orig and amended, or is it the number if I had filed correctly in first place?

I wasn't aware that I misunderstood the rule about adult dependent and didn't claim an elderly aunt that my cousin and I split to put in a board-and-care.  In 2020 - made-up numbers  - I paid 5k in federal and got 10k refund from CA.  In  my amended return, the numbers now say I get a 2k refund from fed and 5k refund from state.  Is this how much I get or am I getting 7k from fed (2k-(-5k))=7k, and have to pay 5k (5k-10k=(-5k))?
