I recently filed my taxes for 2025, but am concerned I made a mistake by not including USDC-to-USD transactions on my 8949. In 2025, I sold ETH for USDC on Coinbase, then withdrew funds to my bank account. Part of this withdrawal process involved converting the USDC to USD. I received a 1099-DA from Coinbase. The 1099-DA showed ETH to UDSC sales. I reported these sales on my 8949, adding cost basis and ETH purchase dates from my records. I paid taxes on the gains. The 1099-DA also showed the USDC to USD conversions. I did not include these transactions on my 8949. They had no gain or loss.

Did I make a mistake by not including the USDC-USD transactions on my 8949? Should I amend my tax filing to include these transactions?
