Disallowed section 179 deduction - Regular Tax and QBI deduction

[shriram51]

Where can I find regular tax disallowed section 179 deduction for years 2018, 2019 and 2020. I checked my previous years' tax returns and can only find QBI deductions (not regular tax disallowed)?

On my 2021 tax return, Turbo Tax needs me to provide information for the past three years in the following categories:

Regular Tax - Disallowed section 179 deduction

QBI deduction - Disallowed section 179 deduction

You can look of form 4562 on line 13 Carryover of dissallowed deduction. It shows the amount of your section 179 deduction that is not allowed in the current year.
