Investors & landlords

I'm having the same problem with my son's taxes.  It's 9 transactions that add up to $1.81 Robinhood Securities LLC.  There's no "Cost or other basis" or "Gain or Loss".  There's a Cost Basis Factor under additional info.  Turbotax is asking for "Date acquired" and "Cost or other Basis".  I'd appreciate any help.  Thanks in advance!
