After you file

The steps in TurboTax Windows will be similar to TurboTax Online.

If you already filed your 2022 return you might not need to amend your return because you had only a loss, therefore, you won't have a taxable event and it won't change your return. TurboTax will only add an explanation statement.

If you didn't enter the Roth contribution then you don't have to enter it since you removed the contribution by the due date.

If you still want to amend your 2022 return to add Form 1099-R for the return of excess contribution then please follow these steps in TurboTax Desktop:

 Click "Federal Taxes" on the top and select "Wages & Income"

1. Click "I'll choose what to work on"
2. Scroll down and click "Start" next to "IRA, 401(k), Pension Plan (1099-R)" 
3. Answer "Yes" to the question "Did You Have Any of These Types of Income?"
4. Click "I'll Type it Myself"
5. Choose "Form 1099-R, Withdrawal of Money from 401(k) Retirement Plans, Pensions, IRAs, etc."
6. Box 1 enter total distribution (contribution minus loss)
7. Box 2a enter $0
8. Box 7 enter J and P
9. Click "Continue"
10. On the "Which year on Form 1099-R" screen say that this is a 2023 Form 1099-R.
11. Click "Continue" after all 1099-R are entered and answer all the questions.

Please be aware, code P will say in the drop-down menu "Return of contribution taxable in 2021" but you can ignore that since the follow-up question will tell TurboTax that it will be taxable in 2022.
