RMDs: Does TurboTax know if I distributed enough?

Since there are severe penalties if I distribute LESS than my calculated total RMD for the year, does TurboTax know if my actual 1099-R distributions are enough, or if I will incur some penalty? 
How does TurboTax know what my total calculated RMD is, since it depends on the full market value of each investment as of 12/31 of the previous year?
