@kykarot I'm trying to share with you a TurboTax Help Article that explains how to enter a 1099B into the TurboTax program. You'll need to use TurboTax Premier or a higher online edition in order to enter investment income. I'm hoping this will work, as this new Community format is quite a learning curve for me!
