I have several transaction listed on my 1099 under "undetermined term transactions for noncovered tax lots" from the Grayscale ETCG fund, which show proceeds, but 0 quantity for each transaction. I consulted my broker about these transactions and was told I wasn't responsible for them. The transactions represent Grayscale selling small quantities of shares - something related to their own tax situation. What I'm trying to figure out is how to deal with this in turbotax, since it imported these entries into my tax forms and is asking me to provide additional information. Does anyone know the best way to deal with this issue? Can I simply delete the entries from Turbotax? Or should I keep the entries and input all 0s? Thanks for your help.
