IRS Free File Program Limitations?

Hello,

 
Before I spend multiple hours inputting data into this program only to find it won't cover my tax situation I am wondering if anyone can shed any light on its limitation(s)?
 
To be clear, the program that I am asking about you can find it at the IRS website here:
 
This will eventually lead to this TurboTax site here:
 
Please note that this is NOT the $0 TurboTax Free Edition product shown on the TurboTax product website
 
I am retired and will definitely meet the less than $39,000 AGI limit to qualify for the program. However, my income comes from IRA distributions and other investment income. The investment income is comprised of stock dividends, mutual fund dividends, and capital gains.
 
Well, I just stumbled upon this on the TT website..."The IRS Free File Program delivered by TurboTax is geared towards lower-income filers, regardless of tax return complexity, and is only offered through the IRS Free File Alliance (FFA) program. No upgrades are available".
 
So it looks like it should meet my needs. So can anyone who has used this program please confirm?
 
Thanks,
Steve
