Hi marialtd
Welcome to the forum, you might want to have a look at the following FAQ which explains where everything is
Welcome to Benefits and Work .
It is perfectly OK for you to type your answers and attach them as extra pages to the PIP form, just make sure that each page has your full name and NIN at the top and that they are numbered, we recommend "page X of Y" so that it is easy to see if pages are missing. Make sure you clearly mark on the form where your answers are and on the relevant page that you are answering question X.
Attach the pages to the back of the form using a staple or make a hole in the top left corner and use a treasury tag, string or ribbon to the form. The pages need to be easily detached so that they can be scanned by the DWP.
If you have any further questions, please come back to the forum.
