I want to file only my return, not my spouse's, what do I do?

Are you using TurboTax CD/Download or TurboTax Online?

I have the same question. I'm using turbo online. I already filed the wife's. I prepared the couple's returns together on online but I only want to efile the husband's as hers is already filed. When I get to the review, it is asking me for her access code, but I don't want it refiled? 

When you are on the Filing Hub page, you'll have NETFILE separate buttons for each spouse. Just click on the one for the spouse who you want to file.
