If you use the CD/download product, it includes a "what if" feature that would allow you to make that comparison. With the online product, you would need to create three separate accounts to look at one married filing jointly tax return and two married filing separately tax returns.
As an alternative, you could use Taxcaster which is a estimated tax calculator: https://turbotax.intuit.com/tax-tools/calculators/taxcaster/
