If you and your wife are the only members of the LLC and you live in a community property state, you file as a "qualified entity". This means that you each file a separate schedule C listing half the income and half the expenses (assuming she materially participates in the business and is not just an investor.)
Otherwise, you must file a partnership return form 1065 for the LLC. This requires Turbotax Business, which is a separate program from the various versions of Turbotax for personal returns and is only available as a download or CD for PC, there is no Mac or online version. Partnership returns are due March 15, not April 15, and the late fee is $195 per month per member. As part of filing the 1065, you will create a K-1 statement for each member, which is listed on the member's personal tax return. (You and your spouse would each list your K-1s on the same return if you are filing jointly.)
Now, if this is a single member LLC and the other spouse works for the LLC, the situation is simpler. Write back if that is the situation, but you originally said "we" started an LLC.
