I've seen a couple of questions about this going back to 2019 that it has been eliminated.
However, IRS Pub. 463 still shows this deduction as available to persons subject to USDOT rules and regulations, in fact, there is a current guide book for preparing 2022 taxes, yet TT does not include this deduction. In my case, my deduction for my meals/expenses on the road as a truck driver puts me over the standard deduction by 15%, meaning I would owe almost ZERO, instead of a large amount.
Why the discrepancy?
