If the Required Minimum Distribution (RMD) amount is not specified on your Form 1099-R, you can calculate it using the IRS Uniform Lifetime Table. Here are some steps:
Calculate the RMD:
Do not try to calculate your own RMD unless you think you did not take the required amount.
The custodian will tell you the exact amount if you have not already been notified.
there is nowhere on 1099-R for the RMD to be supplied to you.
Due to TurboTax issues,
to avoid wrongful penalty, for each 1099-R, tell TurboTax that the distributed amount is the calculated required amount.
