Only you can decide what to do, it is your claim and only you profit or lose by the Decision that will result.
If you need more time then you can request an extension, you should be able to get a two week delay for returning the form. If you don't think that what has been written is adequate then consider replacing/updating it.
You can request a new form but it could easily take two weeks to arrive, you could use the time preparing your answers so you only have to add them to the form. Contact the number on the letter that came with the form.
