Deductions & credits

I have a related issue with a car purchased in 2018.  The max allowable depreciation was $18,000, so after §179 and bonus depreciation, no allowable MACRS depreciation remained in the first year.  The Asset Life History form however shows an addition $6,130 for the first year (2018) which was not actually taken.  It does not seem we are able to override the values in this form, but how do we correct any values in the Asset Life History, or current depreciation amounts?
