I have 1099-INT totaling over $1500. I'm not seeing anything on Turbotax about the Schedule B form I know I need. Should it automatically populate?

Since you have interest of $1,500 or more your tax return will automatically include the Schedule B.

Okay, so the form will be included on the filing but I won't actually see it (or anything about it) in the Turbotax software?

The Schedule B only lists interest and dividend income.  There is nothing more than that so you do not need to see the actual schedule.

But if you wish to do so and are using the TurboTax online editions, you can pay the TurboTax account fees and view or print your complete tax return before filing.

Click on Tax Tools on the left side of the online program screen.  Then click on Print Center.  Then click on Print, save or preview this year's return.
