Hi,
It seems you have a similar issue I faced. I had Crypto with Robinhood. I had a meeting with a TT representative too, with no success. Here is how I got my issue addressed, and I was finally able to print and e-file.
"If there are many crypto transactions, then the printing and e-filing fail. Uploading csv or direct connection with Robinhood seems to generate too many records. Instead manually insert the total crypto Proceeds and Cost or Other Basis, which will consider just one total gain or loss. In that case, there is an option to attach the PDF version for Crypto (Form 1099 Composite in Robinhood Crypto) as proof.
That solved the issue for me."
