After you file

You are filing a joint return.   You cannot also list her as a dependent.  It cannot be both.   You never list a spouse under "dependents."   You just file a joint return.   You are confusing the fact that you support her with what you actually put on a tax return.   Do not enter your spouse's name under dependent on a tax return.   You enter her information once---as a spouse.
