The confusion seems to arise from the ambiguous use of the word "account" in the replies: "login" accounts and "interest bearing" accounts. For the TurboTax reps reading this thread, your users have ONE login account to Ally. Within Ally they have several interest bearing assets, called accounts, that need to be reported in TurboTax. Interest bearing accounts within Ally could be a money market account, an online savings account, and a CD accounts. The 1099-Int reports each of the interest bearing accounts on it. If I have a money market account, a savings account, and two CD accounts, then the 1099 will report FOUR accounts on it (each asset has a different account number). When imported into TurboTax only ONE of the FOUR interest bearing accounts is imported and the other THREE are missed.
I have a CD ladder setup at Ally so my 1099 actually reports TEN different account numbers. The bug in TurboTax of missing 9 of the 10 results in 1) a notable amount of unreported interest, and 2) a lot of manual entry to correct it.
