Deductions and Write-Offs

Yes and no.

Technically, I would code it to a contra-revenue account, something like Sales Returns and Allowances (that would be a general ledger account for a business that sells products). So you would debit or increase that account on the income statement and credit or decrease your bank balance on the balance sheet.

The effect would be that it would lower your profit (bottom line). So in that sense, it’s like a business expense, but it’s not actually an expense, it’s a reduction to overall revenue.

Because DoorDash, GrubHub, and Uber Eats are all online food ordering and delivery platforms, you’re basically doing the same activity, just for different companies. Therefore, IRS will consider them one business. You should file just one (1) Schedule C for all three activities. On the other hand, if you were also doing a completely different activity, such as landscaping, you would need to file two (2) separate Schedules C, one for the online food delivery activity and one for the landscaping work. May you have a successful and safe business!
