There are several compatible aggregators that can be used to help with the import:
Only one .csv file can be uploaded at a time.
In general, the .csv file should be provided via download from your cryptocurrency platform.
The columns for your .csv file should be resorted to match TurboTax, ideally. The compatible aggregators should provide you with this. The .csv file would include details in columns left to right:
- Service name (examples: Coinbase)
- Asset name (examples: Bitcoin, Ethereum)
- Date of purchase
- Cost basis
- Date of sale
- Sale proceeds
If you have more transactions than can be uploaded into TurboTax, enter them in summary form yourself according to whether they were held short-term, one year or less, or long-term, more than one year.
Then, within three days of submitting your tax return, send Form 8453 with your cost basis details from your aggregator service.
