How do I change the taxpayer associated with my account? Last year I did my aunt's taxes. This year I need to do my own.

I am not doing her taxes this year.  Last year I was married filling jointly.  This year single

It would be best if you started a new account to file your own return. It would be difficult to erase or clear all entries of your aunt's that may carry over. You can use the same email.

Yes start your own new account.   Online is only good for 1 return. But you can use the same email address for 5 accounts. Start another Online return here. Sign up and start a new account.
