What do you mean the wrong turf builder?

Triple Action for southern lawns says “do not use on bermuda grass” on the bag. I have a bermuda grass lawn.

Unfortunately, short of vacuuming up the fertilizer, there is nothing you can do. Just water it thoroughly and frequently to flush whatever it is in the product Bermuda doesn't like down below the root system. You may get some die off or dead patches but as aggressive as Bermuda is, it should fill back in. Or you can overseed if necessary.
