Stimulus check

What is TurboTax really doing to ensure that they deposit the stimulus checks into the right accounts? Because they deposited my stimulus check into my ex girlfriends account no problem my STIMULUS CHECK  gone. Finally found out today check to IRS website said they deposit into a bank account ending in 7078 I assumed all this time that I was going to get a “card”so they say in the mail. I found out today that was my ex-girlfriend’s TurboTax account ending in 7078 go figure thanks TurboTax. Great job on  improving that you put your stimulus checks in the right account.
