I have read everything I could on this subject but something is missing. I entered my home office business expense as required under the business section. As soon as I input the "entire mortgage interest" as requested in TT, it increased my refund by $1,000. What I was trying to do is enter furniture expenses of $1,100 and $800 (which I did) so that the Safe Harbor Election Form will pop up but I am not seeing it anywhere. Where have I gone wrong? And why the mortgage interest increase my refund even though it is entered elsewhere?
