itemized and standard deductions - married filing seperately

Hi, I am doing "sample" tax returns on turbotax. I itemized deductions due to excessive medical expenses, and my federal deductions for me will end up being $24000, which will save me much on my return.

Where I need help is with my wife. She has very minimal deductions, which do not exceed the medical threshold amount. I thought she could not receive the standard deduction of 12550, yet when I'm doing the sample tax return for her, it shows 12550 for "federal deductions we found for you". I thought under this category it would be 0 since we were itemizing.

Someone please help - is the 12550 amount being shown correct for my wife even though she has very minimal deductions?

Thank you!
