Filing a 1040X to include K-1

I may have already posted this question so apologies if I did.

I've already filed my 1040 but I may have a capital loss from the sale of a home that was in a Trust. If I do indeed need to file the K-1 in the 1040X what is the simplest way to accomplish this?

Also, it's my understanding that adding the K-1 will automatically populate (in this case a loss) schedule D and I'm limited to $3,000/year to have capital losses offset capital gains.

Finally, I read that the K-1 can only be filed once the Trust is closed. Is this true?

Thank you for the help!

Wait until your federal and state returns are accepted by the authorities before considering an amendment. If you receive a Schedule K-1 in your name with taxable income for any tax year, that must be reported on your individual tax return regardless of the status of the trust. If you receive a K-1 for tax year 2025, that income must be added to your tax return that was already filed.

Whether the Trust issues a distribution of taxable income to you or is issuing its final distribution of taxable income in the closing year will depend on the status of the trust and its tax character; different rules can apply, for example, if the trust is a grantor trust, Subchapter S trust, or some other type. Is there more information you can provide about the trust type and its activities for the year?

Any excess capital losses reported to you above your $3,000/year limited will be carried forward to future tax years; until you report the capital loss carryforward, you will not be able to claim it against future gains. Instructions for filing an amended 1040-X:

What should I know before amending my return?

Here are some things to know before you begin:

Make sure you really need to amend.

Wait until your return has been accepted (or mailed if paper-filing).

Use the same TurboTax account you used to file your original return.

Once you begin your amendment, you'll see your original return. Only make changes to the areas of your return that need amending. The refund calculator will start new at $0 and only reflect the changes in the refund or tax due.

Any changes you make to amend your federal return will automatically be transferred over to your state return.

Thank you, Melinda, I believe I agree with you about filing a 1040X. For the home trust their is no capital gain but rather a capital loss (for commissions, expenses, etc. = ~$50,000) since the house was sold for the FMV = $700,000, sales price = $700,000.

Both my wife and I are retired and we only made ~$100,000 in 2025 in IRA RMD, interest, dividends and my wife's SSA. The only taxes we paid during the year were $300 on the IRA RMD. TT said we owed no taxes and actually had a $222 refund. So I don't know if it's worth the trouble to file a 1040X since the capital loss wouldn't do us much good. It would nearly zero out qualified dividends. Does that sound right to you?

While qualified dividends are taxed at the long-term capital gains tax rates, capital losses are not used to directly offset qualified dividends, with the exception of the $3,000 all ordinary income allowance (which does include the dividends). You would need to report any capital loss carryover amount on Schedule D to use it in a current or future tax year to offset $3,000 in taxable income or additional capital gains. If you haven't reported the carryover loss, then you essentially would be forfeiting the benefit.

There is an outstanding question of gain/loss on the sale of the home, because the basis in the property to the trust would be its adjusted cost basis and not the FMV at the time of sale. Proceeds - basis = gain/(loss).
