Investors & landlords

This is for 2021.

 

Indeed, if I put 12/01/2020 as "Date I started using it in this business", then I get to $1,457 "depreciation deduction". And AMT depreciation deduction is $1,455 (Off by $2).

 

Is this turbotax limitation that it rounds up date to mid month? Or is that IRS requirement?
