If you attempted to e-file your return and it was rejected, review the rejection error code and the explanation carefully in order to resolve the error.
To remove a Schedule C from your tax return, in TurboTax Online, return to Wages & Income and select Self-Employment. Any self-employment income previously entered or line of work profile should appear listed there. To remove any of these entries, click on the trash can icon that appears next to the Edit or Review button for that line item.
You might wish to review the other topics in Wages & Income in case you inadvertently entered information in one of the sections where Forms 1099 are entered.
If you wish to start over and change to a different TurboTax product, see the discussion in this thread (although it is from 2019, the process is essentially the same).
You are confusing ... you asked to remove a Sch C and a Sch E ?
