Can I start a new return instead of using the original one? I've made too many mistakes & want to start a new one. But it would leave an unfiled return in my account.

I've already registered my product so I can't just delete it & begin again.

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

Or if it doesn't let you clear and you haven't paid and 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.  Start an Online return here,

in List of Forms, delete or zero out all the forms you entered.

That is essentially starting over.
