I am trying to get started on my tax return, but it just pulls up my Mother's info. How do I get to mine?

The TurboTax online editions are only for one tax return per account and User ID. 

You will need to create a new account with a new User ID to start another tax return.

Or -

If you used the same account to complete your mother's return after you completed your tax return, then the second return overwrote the first tax return.

Are you using TurboTax Online or TurboTax Desktop?  You can't use your Mother's TurboTax Online account to prepare your tax return.  

If you have your own online account but forgot your user ID, refer to the TurboTax Help article What if I forgot my user ID or password?

If you are using TurboTax Desktop, refer to the TurboTax article Transfer last year's return to TurboTax Desktop for Windows for instructions to pull up your tax return from last year.
