A medical FSA is not reported on your W-2 or your tax return at all. The amount should have been subtracted from your box 1 taxable wages before the W-2 was printed. Then, any medical expenses that were reimbursed from the FSA should not be included as deductible medical expenses since they were already reimbursed with tax-free money.
A dependent care FSA should be reported in box 10. That will trigger Turbotax to ask questions about your qualifying dependents, information about the care provider, and the amount of care. If your dependent care FSA is not included in your W-2 in box 10, you need to get a corrected W-2 from your employer.
