We're aware of the issue. We have a threshold of 400 transactions and it sounds like you've exceeded that threshold. This is not the ideal solution, but you will need to Clear & Start Over your return. You can do this without creating a new account. In TurboTax Online, you can access this feature from the left menu, click on Tax Tools, and you'll see Clear & Start Over. I apologies, you will need to re-enter all your data again.
I will post back here how you can enter your Crypto transactions.
