In my case, my gross income is $8000, my other expense is $1000, so my Gross Income Limitation should be $7000, but TurboTax shows -$1000, so I can't claim any rent I paid as expenses.
In the interview, TurboTax says "Because the net profits for your business was zero or less, which means you can't get the home office deduction".
This is really weird that TurboTax has this error...
