i am redy to file but keep running into a "check this entry" about the school district... but it won't let me update it

Go back through your forms to determine what needs to be corrected. If this is unsuccessful, see if you can go back and delete the school district information. You can also try to delete forms in your return regarding the school district. To delete.

1. Log into Turbo Tax 
2. Go to Tax tools in the left navigational pane of your return.
3. Go to tools 
4. Go to delete a form
5. Scroll down the list of forms, look for any form referencing the School District. Sometimes it is listed as ISD.
6. Select delete.
7. Recheck your forms to see if it has been deleted.

If you are using the software, go to the forms mode in your return and delete the school district forms that appear.

I deleted 2 forms regarding the school district but now it is asking me to fill this out, but I still am a current resident:

Form SD 100: Residency end date -- Ohio requires that you account for your residency for the full year. Based on your entries, we calculate that you have only accounted for 1 in the year. Please review your entries and adjust.

After you deleted the school district forms, go back to the start of the return and verify the residency is still coded correctly.  You will want to go through the interview questions and verify you are still listed as a resident.
