Hi! My husband and I are filing separately. I accidently said he's filing with itemized deductions. He's actually taking the standard deduction. How do I change this?

Not of problem. You can enter itemized deductions in Turbo Tax and still take the standard deduction should the itemized deductions be less that the standard deduction that Turbo Tax will apply to your return. If you do not want to go through the trouble of entering all or some of the itemized deductions, simply select "edit" for that section and erase the itemizations.
