the TT purchase site has high level comparison of the versions, I've always used premier for any additional features related to investments, tax history etc. Given the discounted price why not just get premier.

Re your estimated tax you'll be able to input these on the deductions screens as others have indicated, you certainly shouldn't pay twice the question is any penalty due to timing - if your sales and estimated taxes were large and uneven timing throughout the year you may need to specify the timing by quarter on Form 2210 to avoid/reduce any penalty.
