1099-R Teacher Retirement RMD Trouble in TurboTax

I have a regular teacher retirement plan with monthly payments.  When I try to enter the data from my 1099-R it keeps asking me about age, RMD, etc.  This is not a plan that requires an RMD.  How do I just get TurboTax to accept the actual numbers from the 1099-R without trying to tax me for not withdrawing the RMD?  There is no RMD required for this retirement plan.
