You may wish to phone Robinhood customer support since that will be the quickest thing to try. Email is not a secure method.
Or if Robinhood can't help, see if TurboTax Support has any suggestion for you:
If you are an Advantage member (annual subscription), log into your Advantage account and scroll down past the FAQ links. Near the bottom of the page you should find a special Advantage phone number to directly contact Customer Support.
If you are not an Advantage member, use the form at the link below to schedule a call back, or it may provide a number. Hours are 5AM-9PM Pacific (8AM-12 Midnight Eastern) 7 days/week.
