I have done two different returns before, one for myself and one for my grandson. Filed his but now can't do mine. It keeps going back to his. How do I fix this?

Separate returns would be handled under separate TurboTax accounts. Please see the below FAQ for information on how to recover the password of the second account if needed. Depending on your browser settings clearing your cache or cookies may help if you are having issues logging out of the first account.
