What is the import limit of the number of transactions per brokerage account for CD and online versions?

Today, I was informed by TurboTax CD version that I cannot import from my 
Fidelity account because the limit is 2000 transactions per account.  However, I can import it with the online version.  From web search, I was informed that the online version limit is 1500.  I called TurboTax support, the representative said the on line version limit is 4000.  Which one is true?
