Did they report the CD in the actual 1099B section as a Sale or did you get a consolidated 1099? That will have sections for 1099-Int and 1099-Div and 1099B. You need to enter each section in the right place. So read it carefully and look for headings…1099-Int for interest or 1099-Div for Dividends and 1099B for sales.
I would think if they reported it as a 1099B sale you should enter it there. That's where the IRS will be looking for it. You would enter what you got when it matured and what you deposited to the CD originally as the cost. The difference would be the gain or interest. Maybe it wasn't a regular CD but an investment account.
I would double check with the broker or fund company about it.
