I received a single 1099-DIV (American Funds) with 6 different lines, one for each fund. Each has a separate Fed ID #. Do I need to make 6 1099 entries?

You can, but you don't have to. You can just enter the total amount of the funds in the respective box of the one 1099-DIV. As long as the total amount matches, that's all that the IRS is looking for.  When asked for the EIN, just enter the main one that appears on the 1099-DIV form (your broker's EIN that issued 1099-DIV).

Ran into this at the AARP/TCE volunteer tax preparation site I help out at and I must respectfully disagree. From Fidelity's 2018 Tax Reporting Statement:

"Tax reporting information is supplied to you by each mutual fund as a separate entity.  The IRS requires Fidelity to report each mutual fund separately and not to include an aggregate total of all funds.  Report these amounts on the appropriate IRS Form 1040 for each mutual fund.  Do not report amounts in aggregate under Fidelity Investments."
