Might be an improper file setup at the Provider's end. (Happens a lot for ALLY).
Just enter your extra ones manually ( "I'll type it in myself" )
..... be careful, the last form may be a combined total.
Don't enter the individual ones and the combined one.
Happens to me too. It's horrible that TurboTax has not fixed this. I only caught the error by accident. And my account is not with Ally.
As SteamTrain pointed out, TurboTax is not creating the 1099-INT data, it is only receiving it from another institution. It is hard to know if TurboTax has anything to fix, given that they are only half of the equation.
This is a good reminder that you have to always doublecheck any forms that are auto-imported.
