I am a physician who was a shareholder of a medical practice and left the practice and sold my shares back. How and where do I report my capital gain from this?

Please provide some additional details:

• What type of business structure; LLC, S corp, C corp, partnership?
• If a pass-through entity have you maintained a tax basis schedule of your investment?
• When did the sale occur?

You should have received a Schedule K-1 from the partnership.  As you walk through the steps of entering the K-1, you will come to a screen that says "Describe the Partnership" and it will give you the option to select that you disposed of your interest in the practice. After you do this you will then say you sold partnership interest and then enter the date, selling price, basis, and gain.  Continue through the interview process. 

This will generate a Schedule D to report your capital gains from the sale.
