I had this issue last evening and entered the information on Info Worksheet near the dependents name as Lisa mentioned  That solved my problem.  

In my case, one of the dependents turned 13 during the year.  During the error check, ProSeries advised the some of that dependents expenses may be deductible for the period they were 12.  I never found how I could show or enter that?  

There is a glitch in the software for kids turning 13 during the year.  You need to override the form and disable error checking when you convert the file for e-filing.

Yes, that worked, thank you very much!

Had same issue.  Recommended solution solved the problem.  Thank you.
