I agree with you, however there is one situation, the situation I happened to encounter, where checking this box is the correct thing to do yet TurboTax (the program) then does not go to adequate lengths to help you get the right result. It is when your PFL amount is included on your W-2 (in my case because my company uses an administrator to distribute the funds). The program actually assumes your entire W-2 amount constitutes your PFL payment and puts the onus on the user to correct it.
