How do i deduct expenses for a truck driver like meals showers etc?

[DoninGA]

If you are a W-2 wage employee then none of your employee business expenses are deductible on a federal tax return due to the tax code changes in effect for tax years 2018 thru 2025.

If you are an independent contractor, then you are self-employed and you should be entering your self-employment income and expenses on a Schedule C.

See this TurboTax support FAQ for a Schedule C - https://ttlc.intuit.com/turbotax-support/en-us/help-article/import-export-data-files/enter-schedule-...
