All of those should work with Federal Free Edition as they can all be reported on a 1040A. (Indeed, I personally have an SSA-1099, 1099-INT, and 1099-R for disability pension; I also know the 1040A will accept a W-2 & 1099-DIV.) However, if you itemize deductions that requires a long-form 1040, which will bump you up to Deluxe (the lowest-level paid version of TurboTax Online).
If your income meets the guidelines, you may also want to consider Freedom Edition (at
www.taxfreedom.com or thru IRS Free File), which will file a long form (and also a free state return). However, if you've already started your return on turbotax.com you will need to create a new TurboTax account for Freedom Edition due to IRS Free File guidelines.
