Yes, your investment company likely sent a copy of your 1099-B to the IRS. However, TurboTax may still need you to upload a copy for verification purposes or to ensure all information is accurately reported.
- TurboTax will prompt you to upload a PDF copy of your 1099-B if:
- You've made adjustments to your investment income.
- Your cost basis isn’t reported to the IRS.
- If the 1099-B is not uploaded, TurboTax will need to generate Form 8453, and you'll need to mail a paper copy of your 1099-B along with Form 8453 to the IRS.
For more details, you can refer to the When do I need to include my 1099-B with my return and About Form 1099-B on the IRS website.
