the only thing i can come up with is that you have multiple activities where you took section 179. there is a 4562 worksheet for each activity and one for the total. you must go into each separate activity's 4562 and on line 12B of the smart worksheet select how much of the total allowable 179 you are taking for each activity.
by the way, if you don't want 179 carryovers, you prefer to deduct as much in possible in the current year, you can delete the 179 deduction and instead select bonus depreciation. it is not limited to business income like 179 is. just enter 0 for 179 and bonus should compute automatically.
