Get your taxes done using TurboTax

I realize this is an IRA brokerage account.   I have not started taking IRA distributions yet.  I believe I  have until next year when I'm 72 yrs.  to start these mandated minimal distributions.    Did I just begin this by accident?

What does this mean or what I should know now? 

(I also think I found the section of the Tax Return where to enter 1099-R info)

Thanks again.
