Deductions & credits

Where in TT interview should I enter computer purchase for trading? Is there a $$ limit?

Does Audio equipment (hands free audio headphone for trading education) count as deduction?

 

For hardware purchase there are 2 deduction, One is actual deduction and 2nd is depreciation (I think that one is section 179). Does TurboTax automatically fills out 179 form? If I a filling out on my own how do I link to sch C or some other 179 related items coming from K1? Right now I don't see any form 179 in Forms modes?

 

On Sch C, Line 25 is Utilities as Business expense. What kind of Utility expense will go on Sch C line 25 vs Home office deduction (form 8829)?

 

I don't any income on Form C this year. Technically I can still fill out Form 8829 (Home office deduction) to carry over those expense next year as situation may change? Worth it or may be?
