This is a turbotax issue (BUG) because the business use % changed
if you were to view the asset life history Turbotax would think the first-year depreciation was 9312 because it would use 72% for the first-year business use. Depreciable basis first-year thus 361511 (72% not the real %) put into service in April.
PUB 946 table A-6 factor for year 1 April 2.576% * 361511 = 9312
so turbotax thinks you have under-depreciated the property and will do a catch-up (which is wrong and may even be in violation of the tax laws which would normally require you to amend if all years are open or file form 3115 if one or more years are closed and thus can't be amended) for each year
9312-6159= 3153
remaining life 26.7917 years
3153/26.7917 = 118 additional depreciation per year so 13146 which is correct turns into
13146+118=13264
however in another place in the asset information it uses the depreciation actually taken in prior years
Turbotax should only be using the IRS table % applied to the depreciable basis for the year but I see no way to select this. Your situation will become even worse if the % business use changes from year to year because Turbotax, based on how it is now, will continually correct all depreciation taken
for example, if business use dropped to 10% TT would assume all prior depreciation and current year should have been based on 10%
same as above
first year should be 1293
-6159=-4866/26.7917 = -182
actual s/b 1826 but TT 1826-182=1644
your choices are to let it ride, override which will prevent e-filing, or use other non TT software unless TT fixes the bug.
