Everything is generally correct except for the phantom $1. If you transcribed everything correctly, the program is thinking both that care cost $1 more than your FSA reimbursement, but also that you were reimbursed $1 more than the care expense. I would delete form 2441 and start over again and see what happens. If you are entering dollars and cents, try entering only whole dollar amounts, it might be a rounding error.
If it happens again, and you are using the online program, you may want to call to speak to someone who can look at the hidden program worksheets to see where this extra $1 is coming from. If you are using the program installed on your own computer, you can switch to Forms mode and examine form 2441 directly.
As for question (D), you already indicated to Turbotax that you had a $1500 benefit and forfeited $500, that means you received $1000 from the FSA. If you don't enter qualifying expenses, that reimbursement is added to your taxable income with the notation "DCB" to indicate why line 1 is more than your W-2 wages.
