How do I clear my son's 2019 information in free edition to start a 2020 return for myself?

As long as you haven't submitted payment, deducted the TurboTax fee from your refund, or registered, you can erase his return and start from scratch in TurboTax Online. Please see the FAQ below for more information:

Each person’s tax return needs a separate account. Don’t clear your sons information from his 2019 account in order to replace it with your information for 2020. There are a number of hidden program worksheets and you probably will not change everything successfully. Instead, make a new online account for yourself.
