Self-employment Tax payments

My wife started selling stuff on eBay and made enough that in going through the business section of Turbo Tax it shows a self-employment tax amount - under Business Taxes.  I see that Turbo Tax creates a schedule SE, but I am wondering, does the self-employment tax get deducted and sent off from within Turbo Tax when I file - do I need to do nothing basically?  Or am I supposed to print something out like the schedule SE and submit the amount it shows with a check to the IRS?  Never had to deal with that before, so I'm not sure how that process works once I enter her eBay sales and expenses in Turbo Tax.
