Corrected 1099B

bobomsk — Tue, 24 Feb 2026 06:30:35 GMT

I received corrected 1099B after filing deadline.

It would decrease carry forward loss by $136 since they added one transaction.

It will not change my tax liability for 2022 or any income.

Should I file ammended return now or just change loss carry forward by that amount on next year return?

Thank you for the input.

You must amend the return to correct the carry foward properly ... this can be efiled up until 10/15 to make things simpler.

See this TurboTax support FAQ for amending a tax return - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-return/amend-change-correct-return-a...

I'm not sure of the "official" answer, but if it was me, I would not bother with an amended return. The loss carry forward work sheet is only for your records and is not sent to the IRS.

I would just change loss carry forward by that amount on next year return.

Thank you.

My concern that it adds one transaction on 8949 box b for 136$ and changes total proceeds by that amount.

It is very small amount considering total proceeds of 90k.

It doesn't change anything on this year income or deductions,just slightly decreases carryforward loss.

When I tried to do 1040x it changes nothing.

IRS helptool is not addressing this situation.

It seems though kind of confusing to file ammended return for this when i can just correct carryforward loss on the next year taxes.
