Do I need to file taxes for GoFundMe money?

Sure. It is probably considered income to you but could be different based on the cause for which you were collecting the money. I assume that you are not a 503(c) registered Non-Profit Corporation who has been approved by the IRS. If not you probably would have to pay taxes on this money. In any case you really need to get professional tax assistance before proceeding as the ramification could be excessive.
