Choosing the right Deduction Type for Definitely Related Expenses in Form 1116

Hello Community,

 

I'd like to get your guidance with regards to the deduction type to select when entering Definitely Related Expenses in Form 1116.

 

I have calculated my expenses, but I need to choose the deduction type:

Should I choose itemized or to deduct from gross income? What are the implications of either choice?

 

I have noticed my Federal Due bumped up by $3,000 when I entered my expenses for this form - what can be the reason for that? Am I missing any type of adjustment?

 

Thanks!!
