don't know what you did or what version you are using. I have Desktop Deluxe and created a fake 2023 return using what you provided for 2023 and came up with the same numbers for 2023. when I transferred 2023 data to 2024 and before entering number for 2024 mileage I show a basis of 60660. when I enter 88.07% business usage Turbotax calculates depreciation as $10685.
Your issue may have been caused becuaseTurbotax had some issues with the depreciation worksheets in 2023 and even early in 2024
the 53429 is depreciable basis 60660* 88%
and 20% of 53429 is 10685. My Turbotax does show prior depreciation of $2305
as for the TurboTax number which is wrong because it's trying to apply the 88% usage to year 1 resulting in under-depreciation that it is incorrectly trying to correct.
here's what I think Turbotax is doing
60660 *.88 = 53429
53429 /10 = 5343 what Turbotax feels you should have taken in 2023 because it's using the 2024 business use % rather than the actual for 2023
5343-2305=3038 which is what Turbitax thinks is the under-depreciation for 2023
3038/4.5 =675 the correction Turbotax is mistakingly applying to the remaining useful life - 4.5 years in 2024
+675+10685 =11360
Totally wrong
I agree with you and your CPA 10685 in depreciation for 2024
If you are using online I'm not sure how to correct the issue without creating overrides that will prevent e-file. with any desktop version you can go into forms mode (not available in online) and review the vehicle worksheet.
this would be what should show on various lines in forms mode
33c, 60660
37 & 39, 2305
65, 5
66, ALT
67, HY
there is no asset life history created by Turbotax.
