Transfer from Coinbase to Cold Wallet, then years later, from Cold Wallet back to Coinbase to sell. Koinly is showing the cost basis as short term (same day) sale for very high capital gains

Support Request

So this is my first time to sell some ETH I bought back in 2020 on a cost basis of $425/ETH. However, after that purchase in 2020, I sent those ETH to a cold wallet where they sat ever since. Now that I transferred a few ETH back to coinbase to sell for USD, the transaction is showing as a deposit and then sale the same day, which is translating to short term gains.

I have connected my Coinbase account with Koinly and when I pulled the 1099-DA from Coinbase, it's showing there was no cost basis listed. When I download the 8949 from Koinly, it's showing the same thing: Deposit and Sell on the same day in 2025.

How do I fix this in Koinly to have it realize that these original ETH I bought in 2020 are the ones I sold last year?
