I had a computer monitor put in service for 50% business use in 2020. During smart check TT is asking me to enter a value on Rows 9K Special Depreciation allowance deduction and 9L AMT Special Depreciation allowance deduction.
Prior Depreciation was 0. And this issue did not happen last year. What am I supposed to fill here.
Furthermore, if I try to go to Step by Step to see if there is something in the interview that I could answer TT doesn't take me to the relevant section. What can I do?
