Get your taxes done using TurboTax

I followed the previous comments and worked my way through the questions as though I was entering the Sole Proprietorship information the 1st time and simply hit continue a few times on the various issues.  At the end, it did update the Line 9 number.  This was a rough-out estimate for me.  I will need to enter the actual numbers from all my income sources once received, which will likely occur late March.  Thanks to those that discussed their experience.
