Thank you! I determined that starting with my 2021 return (and affecting 2022), my Turbotax return started depreciating the difference between the original cost ($25100) and the 100% special depreciation ($21272) from 2019. I will have to check those returns to see if I owe $ after amending.
What is troubling me now is that in my 2023 return, I can't get past the Car & Truck Expenses Worksheet, Part VI (Vehicle Depreciation Information), box 36i. This box is "Special Depreciation Allowance" and since 2019, for this car, has always been $21,272, which was the 100% special depreciation allowance used in the 2019 return for this car. But when I put that value in now it says "Special Depreciation Allowance is too large. It cannot exceed 30% of eligible basis."
I can get past this if I zero out 36i and put $21,272 in box 37 (Prior Depreciation), but that doesn't seem like the correct thing to do per the instructions. Or I could zero out the Vehicle Basis in 33c.
Either way, the end result is the same -- no depreciation for this vehicle is applied to the return (which is what I want) and the calculated taxes are correct, but the means to get there (what is shown on Form 4562) doesn't look entirely correct.
Is there a correct way to show the prior special depreciation allowance in 36i? Does this matter as long as the end result (calculated tax) is correct?
