This issue is happening because you were initially eligible to defer self-employment tax due to a tax balance due, but are no longer eligible due to being eligible for a refund.

If this does not clear the error, try:

1. Delete the Sch SE that applies--(Sch SE-T is for Taxpayer, Sch SE-S for Spouse)--by following these steps:
   1. From the left menu, select Tax Tools.
   2. Select Tools.
   3. Scroll to Delete a Form.
   4. Scroll to Sch SE-T and/or Sch SE-S and select Delete.
2. Return to the self-employment income & expenses interview in the Income & Expenses section and select Edit/Add.
   1. Select Edit for your business.
   2. Scroll down to Done so that the Sch SE is recalculated. 
   3. Finish any other questions in the self-employment interview and click Continue.
3. Review the return again.
