Amending 1099B on 2024 Tax Return

[Moonlight]

I e-filed my 2024 Federal & New York State tax return on 4/12/25 and I didn’t realize until after I filed that there aren’t any of my 156 stock options trades transactions (Proceeds from Broker and Barter Exchange Transactions-SHORT-TERM TRANSACTIONS FOR COVERED TAX LOTS) listed on my tax return which go on form 8949-Sales and Other Dispositions of Capital Assets. The 1099B section on the 1099 Consolidated form from my brokerage account (Tastytrade) contains all of these transactions but they were not imported into my tax return as they have been in my previous tax returns over the past several years. I might have accidentally selected No instead of Yes when I answered the question: “Did you sell stocks, mutual funds, bonds, or other investments in 2024?” I have a Total Loss of -$3,240.87 and I don’t owe any tax so listing these transactions will not change anything on my tax return if I amend it. Since the Cost Basis, Proceeds and Total Loss amounts would remain the same, do I need to amend my 2024 tax return to show all of my individual options trades?

It will not change the amounts on your 2024 return but amending the return gets you an additional three grand loss to carry forward and that's not nothing.

Since these are all covered tax lots you can amend the return and just enter the sum total for the section into the TurboTax system.  Covered lots means that the IRS already has copies of the transactions.  So this amendment doesn't need all of the individual transactions entered and shouldn't take you very long at all.

Hey Robert, when you say “just enter the sum total for the section into the TurboTax system” are you talking about the Cost Basis, Proceeds, and Total Loss amounts? If so, I had transferred (imported) that information into TurboTax directly from Tastytrade and was reflected on my 2024 tax return.

If the -3,241 Loss is already on your return, you don't need to amend.   You said in the original post that they were not included on your tax return, but then you say the loss was recorded.   

Are you talking about 1256 contracts?   Those get entered in the Contracts and Straddles section of TurboTax.

Hey Dawn, in my original post I meant that the 156 individual options contracts are not listed on my tax return with the exception of one 1256 contract being listed on the return. So is that ok?

[RobertB4444]

As long as the totals for the section are listed and the loss is already shown on the return then there is nothing for you to amend.  You are finished.
