If your distribution is from a qualified account, say yes. 

If money is non-qualified, that means it is not part of a tax-deferred account. Examples of tax deferred account are traditional or Roth individual retirement account (IRA), a simplified employee pension (SEP) or an employer sponsored defined benefit plan such as a 401(k). Taxes have already been paid on non-qualified money.

Nonqualified annuities (those held outside a retirement account) generally have no requirement to withdraw your funds at any age unless required by the annuity contract itself. Some contracts force distributions or annuitization to begin at a certain age, generally from age 85 to 100. A few contracts do not require distribution of the proceeds until death. 

Your 1099-R issuer is required to follow RMD rules and regulations, so if you received a distribution and you're at least 70 1/2 years young, you can be almost certain you received an RMD. Check with your plan administrator if you're still not sure.

Required Minimum Distribution (RMD) rules apply to all employer-sponsored retirement plans such as pensions, profit-sharing, 401(k), 403(b), and 457(b) plans, as well as Traditional IRAs and IRA-based plans such as SEPs, SARSEPs, and SIMPLE IRAs. However, RMDs are not required for Roth IRAs while the owner is still alive.
