Deductions & credits

That must be in the Self Employed version.  I'm using Deluxe and have this screen in the Home Office section:

My whole home mortgage interest is $16,628, which showed at the top originally, then once i put the excess in, it changed to the $10,000 max itemized deduction.  I'm going to assume based on this that they actually want you to insert just the excess.

Thank you.
