You have probably created a return that permits joint preparation of a spouse's return.
As you point out, your spouse cannot file twice in the same tax year.
So, go Tools, Return Manager, Create a New Return , but this time it must just be for yourself.
Pay careful attention right at the start as you will have to uncheck the option to do joint preparation.
Note that you still report yourself as Married and therefore you will be asked to supply your wife's identity and Net Income line 236 amount from her return.
