Why did TurboTax send my return to a random routing and checking account? I e-filed and linked my bank account with my bank login credentials. What do I do?

I have had the same bank account for 25+ years.  I have filed with TurboTax for over a decade, requesting the refund to be into the same account every year. Last year they had me login to my bank account on their site for e-filing via my bank account login credentials.  Nearly a year later and my return still has not arrived.  Looking at my return I now realize there is a random routing and checking number listed on my tax forms.  Why did this happen?  How could this happen? I have no idea who this account belongs to.
