Trouble filling in the How much did you pay for child care in 2021? I paid into FSA but also plenty left over to claim the credit. But system thinks I didn't use FSA.

I paid $5000 into FSA. However, day care was $17,400. I have $12,400 to claim to the credit. However, the system doesn't show any info to differentiate it and thinks I paid full $17,400 out of pocket. How can I fix it?
