declare pip on ilr application

This is turning into a nightmare, I was applying for ilr , under the normal route £18600 income etc, but on the form it asks if you get any benefits , my husband gets pip, but now the form has taken me away from the £18600 route and has literally dozens of extra question, which just seem not relevant if I want to go the £18600 route, do I need to decalre his pip,
