Deductions & credits

So, to further clarify this advice for my situation...

 

The domestic partner in my case became my spouse mid-year.  I reported it to my employer and they stopped imputing the income for the premiums.  So now we plan to file jointly as a married couple this tax year (2019) for the first time.  My spouse isn't my dependent, they're my spouse.  Do they still qualify for this itemization on our schedule A?  What line are we talking about specifically?

 

If we're talking about the Medical and Dental expenses Itemized Deduction, then don't you need to meet a 7.5% AGI requirement (for all medical expenses for the year) to enter anything into this box.  And when you do enter anything into that box, it's only what you were taxed on that rises above the 7.5% level (for TY 2019, it may have been 10% for TY 2018), not the whole amount.  So, for me, I believe that's still $0, yet I have a ton of extra imputed income in Box 1 of my W-2. :(

 

Right?
