Firstly, your DCFSA should be recorded in box 10 of your W-2. Is is there? If not, you need a corrected W-2.
If you enter a W-2 with a dollar amount in box 10, Turbotax should automatically prompt you to enter your dependent care information, because it's an error to file without that. You can also access the dependent care credit directly on the "Deductions and Credits" page, although I don't know exactly how it's called. It might be under "your family" and then "child and dependent care." If you are using Turbotax Online, you might not see all options unless you look for a button like "show more options" or "show me everything".
