Rec'd 1099B dated January of 2020 but transaction occurred in Dec. 2019 and has already been accounted for in last year's return. Now what?

[lif3r8c3r]

Date of the confirmation to request the transaction was 12/31/2019 and that is the transaction date I reported on last year's return. Date on 1099B is 01/08/2020. How can I correct that?

I'm curious about the flow of documents. 

Did you receive a 1099-B for tax year 2019 that included this trade?  If you did then you correctly included it on your 2019 tax return and you will have to contact your broker to resolve the question of having it posted on two 1099-B's.

If this trade was not included on the 1099-B for 2019 your tax return is incorrect and will have to be amended.

After a trade occurs it may take some time to secure the financial transactions.  The final date of transaction is when all monies have been reconciled.  This may have pushed the trade into 2020.

To amend a return 

Some quick ground rules:

1. Be sure the original return was filed and accepted.
2. Save the original return before you start the amendment
3. Change the name of the amended return.
4. DO NOT go back into the return or change anything before you start the amendment process.
5. Gather everything you need before you start.
6. Complete the entire amendment process before you log out.

 You can correct a return that you've already filed and had accepted.  Select the year that applies and use this guide to proceed.

Select your tax year for amending instructions:

• 2020
• 2019
• 2018
