vehicle depreciation issue over the years

We have been using personal vehicle for business.  This year I realized,  the depreciation is not entered correctly in the system or maybe i am missing something. How do i fix it. I don't think the car is 100% depreciated and the 6 year depreciation is not done yet

 

  • Turbotax Had added depreciation for 2022,2023, 2024

  • No depreciation in 2021, and 2025

I am guessing i may have put standard deduction in 2021 (not sure as i can't find that info) and changed to actual in 2022 but i don't see anything this year

Some more data:

purchase price - 45540
2023 - basis calculated by system - 8,671 - deprciation 1779

2024 - basis calculated by system - 6,622- deprciation 1346

2022 - basis calculated by system - 15183 - deprciation 1954

2025 - form 4562 has car in there but no values.
