Q. Do I still need to go through the no 1099b to capture the zero basis?
"Capture the zero basis?" I'm not sure what you're asking anymore. I assumed you had previously received total box 9 (1099-Div) distributions, that reduced your cost basis to zero. That means any additional box 9 distributions are now taxable (as capital gains). TurboTax (TT) does not pick up that income from you entering the 1099-Div. Box 9 is treated by TT as non-taxable. It's up to you to know if it's taxable. You enter it as an investment sale, with $0 basis.
