You will not include your son's income on your tax return.
Based on the K-1 information that you have provided (plus his other income), he is not required to file a tax return. You can double-check (or use this in future years) at https://www.irs.gov/uac/do-i-need-to-file-a-tax-return
Note: If there was federal or state withholding from his other income, you may wish to file a return to get a refund of those taxes.
