How to use Turbotax for R&D Tax credits

My sole proprietorship (single member LLC) is an  R&D stage (early state) biotechnology company, with losses each year and no revenue. In other words, 100% of the company's effort and expenses are on cutting edge R&D. So far, I have not see any place in the TurboTax tax return to enter this information.  Just as an FYI, I am using Turbotax for the first time? Can anyone help direct me to the right location to enter this information? Thank you!
