If you have not paid for the online edition you are using, have not filed your tax return or registered the Free edition, then you can clear your return and start over with a lower priced edition.

Use the TurboTax Free File program if you are eligible - https://freefile.intuit.com/
If you are eligible you can use the TurboTax Free File Program which is free to file both a federal and state tax return. The Free File Program edition is a full featured personal tax program and on a separate website from the TurboTax online editions.

To qualify for free 2019 federal and state tax returns with the Free File Program, you'll need to meet at least one of these requirements:

• A maximum 2019 adjusted gross income (AGI) of $36,000; or
• You qualify for the Earned Income Tax Credit (EITC); or
• You served as active duty military (including Reservists and National Guard) with a maximum 2019 AGI of $69,000 (you'll also need a military-issued W-2).

Intuit did charge me for online filing, but it was rejected by the IRS because I didn't have the ID number. I can't get an ID number because I have no outstanding loans or credit cards.

What ID number do you need and what for?  Do you need your 2018 AGI to Efile?  If you paid you can not start over.  You either have to fix your return or print and mail it now.

How to print and mail your return,
https://ttlc.intuit.com/community/printing/help/how-do-i-print-and-mail-my-return-in-turbotax-online...

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS received the return. Don’t forget state.
Important! Mail Federal and State in separate envelopes and mail each year in separate envelopes.

i need to delete my 2020 return and start over

[VolvoGirl]

If you haven't filed, registered or paid you can try to clear and start over

https://ttlc.intuit.com/community/using-turbotax/help/how-do-i-clear-and-start-over-in-turbotax-onli...

Or if it doesn't let you clear and you haven't paid or filed you could just start a new account.  Online is only good for 1 return per account.  But you can use the same email address for 5 accounts.   How to start another return in the Online version
