Why was I charged by the IRS for my federal tax due when it was already deducted from my CA state refund by TurboTax?

Why was I charged by the IRS for my federal tax due when it was already deducted from my CA state refund by TurboTax?

 

I’m trying to understand what happened to our refund. I was under the impression that our federal tax due of $1,882 had already been deducted from our CA state refund of $2,511, which is why we were only expecting to receive $629.

 

Can someone please explain this to me? Why did the IRS still charge us the $1,882? I’m wondering if there was an error somewhere or if I’m just missing something.
