Is there a way to access my account information? My mother-in-law had set up this account, but she passed away a few months ago. How should I proceed?

I only have access to my daughter's account information, not mine.

Maybe, it depends on how the account was set up. 

You can start by trying to recover the account. Start by following this link. 

Enter your email address and then enter the verification code. The next screen will show you every account name connected to your email and the date you last used it. 

Pick the one that seems most likely to be the one you used last year. You will have to verify it again and will be prompted to change your password. 

If you don't have access to the email address and can't sign in to your TurboTax account, fill out our Account Recovery Request Submission Form.

If the same account was used for you and your daughter your information has been overwritten by hers.  If it is a separate account you can try to recover it but since it belonged to to your deceased mother-in-law you may not be able to access it and should start a new account for yourself.  Only one person can use an online account.
