AMT prior depreciation

Hello,

I almost finished my 2021 tax. In the TTax final review, there are 4 areas that need to be fixed.

On car and trucks expenses worksheets, line 37 Prior depreciation and line 39 AMT prior depreciation fields are pink. I guess I need to fill them in. But what numbers should I put in? This vehicle was using standard deduction last year and I am using actual expense deduction this year.

Thanks,

Jenny
