Medicare 'Extra Help' Household question

My parents currently qualify for the Medicare 'extra help'. It seems that every year they receive a questionnaire that is used to help verify their continued eligibility.

They moved in with me last year though and give me a check every month to cover room and board costs.

When the questionnaire asks how many are in your household, do they need to include myself? They do not support me nor do I pay for any of their monthly fixed expenses.

When I spoke with a tax accountant earlier this year, she mentioned that I did not have to claim the money that they pay me that goes toward food and utilities as income.

Thanks!
