Step 1 - Schedule K-1 worksheet, right side of each stockholder.

Step 2 - If there is a change you need to complete Weighted Average Ownership Percentage Worksheet for each date of change and then enter info for each stockholder.

Thanks.  I was using the weighted ownership worksheet but see now that I have to use 12/30/20 instead of 12/31/20 to make it work.  Thank you for your response.
