If you worked for Uber and DoorDash, you'll need to report that as self-employed income in Schedule C.
Do not report this as DD income as W-2.
If you tracked your mileage in QuickBooks Self-Employed (QBSE), you'll be able to import your mileage into TurboTax, and it'll go into a Schedule C. If you've already started your tax return in TurboTax Online, you'll be able to log into QBSE, go through the Tax Checklist, and send the mileage information to TurboTax, as well as anything else you may have tracked in QBSE.
