2021 filed sched C as a DoorDash Driver. 2022 no DoorDash income, but Turbo wants to keep schedule C. Form 8995 generated and gave a credit. Should I remove schedule C?

You do not need Schedule C, nor do you need to Form 8995.  You can delete both of those.  If you are using TurboTax Self-Employed and don't want to pay for it, you can downgrade, but only by clearing and starting over:

To switch to a cheaper TurboTax Online product, you must clear and start over. This will erase all the info you've entered so far.

If you already paid with a credit card or had the TurboTax fee taken from your refund, it's too late to switch products. If you chose to deduct the fee from your refund, but haven't yet completed the agreement, do this:

1. Select File from the menu
2. Select Revisit next to Step 1 on the Just two more steps and we'll file your returns screen
3. Select View payment options
4. Select Pay with Credit Card, then cancel the credit card option
5. You're able to clear and restart your return

Each TurboTax product supports different tax situations and forms. Review the forms you want to include before switching products.
