Because payments from an annuity are based on your life expectancy, if you received a 1099-R from an annuity, you should say yes, it was your RMD.
If you converted your IRA to an annuity, and you are over your RMD beginning age, it is possible you were required to take an RMD before converting the remaining balance to an annuity. Failing to do this (if required) can lead to penalties. If you are trying to enter your 1099-R forms for the IRAs, we need more information to help.
