Since you are not claiming your child as a Dependent, and are filing as Married Filing Separately, you won't be able to enter Child Care Expenses in TurboTax.
Without entering expenses, (even though you don't want the credit), your FSA will be taxable income, as it was not applied to qualified expenses.
