I have a rental propety, which was on short term rental from Jan to May, and. I sold the property in May. I keep getting error "home sale worksheet link should be blank"

Yes. Here are a few steps that might help resolve the issue:

1. Uncheck the "Sold or Disposed of This Property" Box: In the rental section, make sure you do not check the box that says you sold or disposed of the property. Instead, report the sale under the rental asset section. 
2. Delete the Home Sale Worksheet: If the software is still linking the sale incorrectly, go to Tax Tools > Tools > Delete a Form and remove the Home Sale Worksheet from your return. if in the software, go to the forms mode and delete the sale from there.
3. Ensure Proper Reporting of the Sale: The sale should be reported under the rental asset section, not as a personal home sale. When entering the sale, make sure to answer "No" to Special Handling and follow the prompts to correctly allocate depreciation and capital gains.
