Deductions & credits

None of this pertains to any vehicle or one time bonus.  I have NO $18,000 deduction for vehicle or need for Section 179 does not apply.  How do I correct this and get credit for one time improvements in 2021 of $8590 written off in one year as expenses and capture my carry over Special Depreciation from previous years of $18,191 for reduction of income / taxes? Very frustrating.
