Dependent Care FSA contribution

I contributed 5,000 to an FSA, but Turbotax says I have "$4,850 of excludable dependent care plan contributions." Where is that $150 difference coming from? 

 

I did not carry forward anything. For the last few years I've spent over 10K in dependent care expenses, and get $200 credit (20% of $6,000 (2 kids) - $5,000 in FSA contributions). Not sure why this year Turbotax says I have $4,850 excludable dependent care plan contributions vs $5,000.
