How do I fix the error "Link to QBI Wksht should be linked to an independent copy of QBI worksheet with no other activities linked to it?

The error Link to QBI Wksht should be linked to an independent copy of QBI worksheet with no other activities linked to it  may be related to using a single QBI Component worksheet for multiple QBI activities.  Depending on which version of TurboTax you are using, take a look at the QBI Component worksheet(s) you've got. 

In For TurboTax Online, look at Tax Tools > Print Center on the left menu.

If you're using a download/CD, create a PDF of your return with all the worksheets to see if you have multiple QBI activities and one worksheet.  You can also use Forms Mode to view the worksheets.
