Retirement tax questions

It depends. Do not use the 1099-R in your 2023 tax return if you only made contributions in 2024.  You will get one in 2024, when the withdrawal is made, and the taxable amount will be only the earnings in 2024 because you will not take a deduction for this contribution on your 2023 tax return. You removed it and will act as though it was not contributed in 2023. 

If you did contribute in 2023, then you will have earnings to report for 2023. If you should get that information from your broker or plan administrator.   Next, you can enter a substitute1099-R to include in the 2023 return with only the earnings you received in 2023.  This will eliminate the need to amend your 2023 return when you actually receive the 1099-R in 2024. In this scenario, you will report earnings again in 2024, for only the amount you earned in 2024.

2023: If you enter a 1099-R you will reach a screen 'Do any of these situations apply to you?' select 'I need to file a substitute 1099-R' - see below. You will be required to file by mail using Form 4852. You can click the question mark beside the selection to read additional information.
