No box on the worksheet.  The yellow ? is more like the instructions and purpose of the form.  When I right click on the Tax Due line, it won't allow a Cross Reference. I double checked again today in case there is an update, but that's not it.  I see my only option as an override. 😐

Thank you for your suggestions!  I appreciate you taking the time during this busy season.  If I ever find out what's going on, I'll come back here and let you know.
