capital loss carryover doesn't filled in 2023

[payamps]

First, my capital loss carryover from 2022 is 5000  (numbers are example, not correct numbers)

In 2023 Schedule D:

Line6 Short-term capital loss carryover (5000) I forgot to fill this number

Because I still had loss on 2023, so I got 3000 in 2023  Line21 is (3000)

Here's my questions:

1. Do I need to amend 2023 to correct right numbers in Line6 , but it won't change my taxable income, because I have already got (3000) in 2023.

2. If I need to file 2023 1040x, I seems that my taxable income doesn't change, do I need to amend state tax 2023?

3. if I don't amend 2023, can I directly fill in right numbers in 2024 Schedule D Line 6

I used IRS Schedule D instructions to calculate my correct capital loss carryover from 2023

The last thing is,  I used TurboTax 2023, I e-filed federal tax and paper filed state tax, so TurboTax tells me I can't e-file 1040X, which means I need to paper file 1040X, is that fair?

Yes, you should amend your 2023 to include the 2022 capital loss carryover so that you have the advantage of using it. Any excess will be allowed to be carried to 2024. 

An amendment is the only way the IRS will have the information allowed to be used in 2024.

Yes, you can enter the correct number before you actually file your 2023 amendment, however you will want to complete that return and send it in. Eventually the IRS will reconcile the returns which means you want them to see the accurate picture and not change your 2024 tax return. Reconciliation should be faster, however it can take much time.

• What is the deadline for filing an amended return?

Do you mean that  I only need to file 2023 1040x to federal , no need to state, is that right?

No need to do a state amendment.
