I am applying for a fiancé visa in 2016 and I will still be living with my parents. Can my parents fill out the financial support documentation?

The financial support obligation for fiancés is not as strict as when applying for the green card. I would suggest that you can give a letter explaining your situation and why you are relying upon your parents' support at this time. Then your parents can submit the affidavit of support on form I-134 affidavit of support with job letter, proof of recent payments, bank statement, and last year's tax return. If the Consulate requires further papers, it will notify your fiancé.
