put simply Turbotax cannot handle varying percentages of business use
here's an example
assume date placed into service 1/1/2023
first year businee use
100%
cost 351804
1st year depreciation
351804/27.5 = 12793
1st year you only get 11.5 months not 12 under the mid-month convention for real property
12793 *11.5/12 = 12260 (ok I agree with Turbotax calculation)
2nd year Turbotax computation when business use is 33.33%
351804*.3333333=117268
117268 less 1st year depreciation of 12260 leaves 105008
remaining life 27.5-.958333 (11.5/12) leaves 26.54167 remaining life
117268/26.54167 = 3956 2nd year deptreciation which is totally wrong but this is what TurboTax comes up with (this is what Turbotax comes up with rather than
351804/27.5*.33333
there's no way to fix this in Turbotax except by overrides
