Due to the most recent pro series updates I am having the same issue now for any Ohio tax return that has not been e-filed yet.  Already validated that there is no school district code on any of the W-2s.  The school districts that the clients live in are school district tax free.  If I try to remove the SD-100 it acts like it will delete, yet the form stays on the screen.  Any help is greatly appreciated!!!

I started receiving this error after the last update also. I rarely need to file a school district return based on where I am located in Ohio so I have been doing the following:

If you don't need to file a school district tax return with the Ohio return check the box on the school district return to "Suppress this copy of Form SD 100".

Thank you. That did the trick finally. Appreciate your help

You're welcome.  I noticed it's doing the same thing this year too.

Thank you so much! Error-free (finally)!

You're welcome
