"license linked to another account" - No way to use other 4 licenses I purchased.... Mad as heck.

Just talked to support. I purchased a 5 license copy of Turbotax.  In years past, my kids (living with me) all used this. They created their own turbotax accounts. 

 

Now, Turbotax says, "license linked to another account" and my kids have to log in to MY account --- which I will never let them do.

 

So, Please, TurboTax, tell me... how in the world can we ever use the other 4 turbo tax licenses.... Because.... I don't know ANYONE who completes 5 personal tax returns for themselves.

 

This is sneaky and underhanded. Mad as heck.

 

I would NEVER have purchased Turbotax 5 license edition if I had known this.

 

How do I use the other 4 licenses? It seems to be an impossibility.
