I need help with the one I got wrong. Auto 90% $20,000. Please explain thank you

Casper used the following assets in his Schedule C trade or business in the tax year 2019. Casper is a new client and unfortunately does not have a copy of his prior year's tax return. He recalls that all of the assets purchased in prior years used MACRS depreciation (no $179 expense or bonus). Casper does not wish to take a $179 or bonus depreciation. (Use Table 6A-1 and Table 6A-8) Required: Calculate the current year depreciation allowance for Casper's business. (Round your final answers nearest whole dollar amount.) Answer is complete but not entirely correct. 2019 Date Sold Cost Method Business Use 100% 100% $ 05/15/2019 100% Asset Computer 1 Computer 2 Printer Computer 3 Equipment Auto Furniture 1 Furniture 2 Office building Date Purchased 03/12/2016 05/05/2016 08/25/2019 05/25/2019 03/20/2017 05/01/2019 02/12/2017 08/15/2017 04/01/2019 100% 100% 3,000 2,500 2,200 2,800 2.700 20,000 22,000 3,600 330,000 5yr MACRSS 5yr MACRS 5yr MACRS Syr MACRS 7yr MACRS 5yr MACRS 7yr MACRS Tyr MACRS 39 SL Expense 346 $ 144 $ 440 $ 560 $ 472 $ 3,258 $ 1.924 $ 630 $ 6,003 90% 08/25/2019 100% 100% $ $ $ 100%
