Puzzled by depreciation calculation

[sockfight-1]

I have a business asset that I've been depreciating with TurboTax since 2017. Every year, the amount of depreciation TurboTax calculates has been exactly what I expected... until now. Here are the details TurboTax has in the forms view (form 4562):

• Asset in-service date: 7/27/17
• Cost 16,148
• 100% business use
• Depreciable basis 16,148
• Life 7.0
• Method 200DB/HY

For my 2022 taxes, it reports prior deprecation of 12,545 (as expected) but current depreciation of 1,441 (unexpected).

I plugged my parameters into the depreciation calculator here: https://www.calculatorsoup.com/calculators/financial/depreciation-declining-double.php

And got these results: 

Year, Depreciation
2017, $2,307

2018, $3,955

2019, $2,825

2020, $2,018

2021, $1,441

2022, $1,029

2023, $735

2024, $263

Every year from 2017 to 2021, TurboTax's calculation has exactly matched this web calculator, but this year, it wants to depreciate $1,441 again instead of the expected $1,029. Any idea why?

Thank you.

P.S. On a related note, saying this asset has a salvage value of zero (i.e. worth nothing after seven years) is incorrect. I'm not sure I was asked to provide a salvage value. Would it be better to continue depreciating it to zero and then report a gain if the day ever comes to sell/dispose of the asset? Or would it be better to somehow 'abort' the depreciation at this point?

The calculation in TurboTax is correct.  And you would not be asked about a salvage value under our current depreciation system.

• The rates under 7 Year depreciation are almost exactly the same for year five and six (8.93% and 8.92% respectively).  For this reason the depreciation is exactly what it was for 2021.
