Coinbase import is missing transactions for 2021. I can't add the buy transactions because TurboTax will not let you enter a manual transaction prior to 2024.

I sold BTC in 2024 that I bought in 2021. The import from Coinbase is missing 2021 data despite having older transactions. I can't add the buys because TurboTax won't allow entering a transaction prior to 2024, so it can't calculate the cost basis and gives no way to fix this.
