DCFSA and Child and Dependent care Credit with no box 10

I contributed $5k to my DCFSA (I have one child).  My employer left box 10 of the w2 blank and is not responding to questions so far.  Is there a way to manually input my FSA contribution into turbotax?  Without it, the software is giving me the $600 ($3000*.2) Child and Dependent Care Credit, which I am pretty sure I am not eligible for, right?  Should I just type it into box 10 when I input my w2, or will that create unforeseen problems since it won't match the one being sent to the IRS?

 

The $5k was correctly excluded from boxes 1,3, and 5, and as far as I know it is a normal, plain vanilla DCFSA situation, so it should have been in box 10 right?
