Client bought a truck under 6,000 pounds in Nov 2018 for around $32K.  In 2018 he took $10K sec 179 and $8K special leaving a basis of around $13K.   2019 proseries professional shows 0 depreciation for 2019, 2020, 2021, 2022, 2023 and then depreciation in 2024, 2025 and 2026 to take the basis to 0.  That seems wrong.

In 2018 proseries professional program shows depreciation should be around $4K for 2019, $2K for 2020......  which fits with what I would have thought should happen.  Is this a program error or am I misunderstanding how it is supposed to be calculated.
