Deductions & credits

Thank you for your response.  I'm not entirely clear so just to confirm.

1.  I am *not* itemizing because I am limited by SALT so I'm taking the standard deduction.  Should I still check "yes" that I want to take the mortgage interest home deduction?

 

2. I should have been clearer that I'm asking what amount of taxes I would enter on the "excess taxes paid" screen.  I did enter the total for the home office deduction (which TT will prorate based on %) but should I also enter the full amount for the "excess" as well?

 

Thanks in advance.
