Thanks. It is clear to me that I have to report 2020 Form 1099 R including the Fed. tax withholding for 2020 tax return.
I would like to check one more thing. According to TurboTax, I still need to report a made-up 1099 R (indicating it is for 2020) with 2019 tax return in order to avoid amending the 2019 tax return later (and/or to inform the IRS of the removal). So, I understand that I need to enter the gross distribution amount in Box 1 and zero (0) as no earnings in Box 2a of the made-up 1099 R now. Do I need to enter also the Fed. tax withholding in Box 4 of the made-up 1099 R now, or just leave it blank now?
