I have a 1099-INT from a Schwab brokerage account. The box 1 interest amount is from multiple bank CDs. Does the 1099 box 1 need to be broken out to list each bank CD?

You can just enter the total.  Is there a total on the form?  

Yes there is a total for the 1099 box 1 amount consisting of all the individual CDs purchased throughout the tax year. Just the one 1099 from Schwab. Interest is from 20 different banks, but paid through the one Schwab account and 1099. Making sure the IRS doesn’t need to know the source of each. 

Because it is a brokerage account, you can just say "Schwab brokerage" on one line with the total of all interest paid to that account.
