There are two filing statuses that apply to your situation; filing as single or filing as head of household. Because you are not married you can not file as married filing jointly.
One of the qualifications, among others, to file as head of household is that you pay over half of the household expenses. As the two of you live in the same house only one of you can claim paying more than half of the expenses.
Each of you will have to file your own tax returns. TurboTax will determine the best filing status for each of you based upon the information that you provide to TurboTax.
The link Guide to Filing Taxes as Head of Household has information that you may find useful.
