Please contact a tax professional for tax guidance and return preparation.
The K-1 for your S corporation is generated in the process of preparing Form 1120-S for the corporation. You would then enter the information from that K-1 into your individual income tax return.
TurboTax Business (which is not available online or for a Mac, but must be installed and run in a Windows environment) can be used to prepare an 1120-S for an S corporation (see link below).
However, you absolutely should not attempt to handle this yourself but, instead, have the return prepared by a tax professional who is well-versed in corporate taxation.
