Desktop adding 1099-DA and 1099-B double counts gains

[armadillo]

On the desktop version, I've uploaded by 1099-DA from my crypto platform and Turbotax increases my tax due calculation because I have positive capital gains. However, the cost basis is not accurate. If I import my 1099-B which contains my list of transactions and an accurate cost basis, Turbotax assumes this is extra proceeds and it increases my tax due again. How can I avoid this double counting from happening?

If you've received a 1099-B or 1099-DA with duplicate income, be aware that the IRS will be expecting to see the gain/loss information from both forms (they've received as matching copies) reported on your individual income tax return - and you may need to request a corrected 1099 from one of your investment brokerages to prevent automated notices sent from the agency to you. 

Are you sure that proceeds from crypto / digital asset sales are reported on Form 1099-B? 1099-DA is standard as of this year. Make sure you're not mixing up unrelated transactions that both need to be reported separately - check the Asset Description and Payer's Name on Form 1099-B compared with the Name of digital asset and Filer's Name on Form 1099-DA. 

You can manually update your 1099-DA cost basis details in TurboTax Desktop by following these navigational steps:

1. Federal
2. Wages & Income
3. Select I'll choose what I work on
4. Investment Income
5. Select Update next to Stocks, Cryptocurrency, Mutual Funds, Bonds, Other
6. Select the 1099-DA you imported
7. Select Edit
8. Proceed through the question screens to update your 1099-DA info for accuracy.
